One on one GMAT Tutoring: Your Way to GMAT Success

By: Apex GMAT
Contributor: Ilia Dobrev
Date: 4th August, 2020

When it comes to GMAT tutoring, we at Apex have learned that there are a set of core characteristics that all successful GMAT test takers embody; no matter their industry, degree, personal traits or prior levels of knowledge. In this article, we’ll:

  • explore each of these eight core characteristics
  • deconstruct a few of the faulty assumptions that test takers bring to the process
  • distinguish one-on-one GMAT tutoring as an efficient way for most people to achieve a competitive GMAT score and build a solid foundation for an MBA program.

Many people preparing for the GMAT believe that it’s the instructor’s responsibility to implement their own expertise and style to improve one’s current skill level and address one’s weaknesses. The reality, however, is more of a two way street, where the important element is the compatibility between a tutor’s teaching style and a student’s learning style. A qualified instructor is one that first examines the way a client processes new information and perceives problems, and the techniques he or she uses to address those problems. Only after a tutor has understood one’s learning style can he/she match professional guidance with the needs of the client.

8 ways one-on-one GMAT tutoring gets you to a 700+ score on the GMAT

1. Creating a productive & efficient learning structure

Oftentimes, test takers seek GMAT tutoring because they have stumbled upon enough types of challenging problems that they can’t tackle alone, or they’ve reached the peak of their self-preparation but still seek higher results. One-on-one tutoring differs from self-prep and group work with a tutor in terms of learning environment and having the benefit of an external perception of your performance. With private GMAT tutoring, communication dynamics are on a much more personal, and personalized, level – yielding stronger results much more quickly than alternative solutions.

The privacy and trust inherent in a one on one GMAT tutoring setup permits test takers to feel comfortable sharing their weaknesses in a safe environment and tackle those things that are challenging to them without worrying about how it will be interpreted by peers. The comfort afforded by this situation should not be underestimated. A private GMAT tutor not only helps with improving one’s technique and self-knowledge, but also strives to create a healthy and secure learning environment that is vital for:

  • reducing test anxiety
  • building GMAT confidence
  • improving studying habits
  • avoiding distractions and disruptions of the learning process
  • encouraging freedom to ask questions
  • nurturing motivation

2. Constant two-way feedback

A fundamental rule of management states, “No feedback is bad feedback”. Another is “What gets measured gets managed.” When preparing alone or within a group, a future test taker will not have a clear indication about how effective they are performing until they take a practice exam, and even then the exam only focuses on specific metrics. A good private GMAT tutor will know what to look for, what to measure, and what feedback to give to provide rapid and lasting results. They will guide you through questions that are matched to your current level of skill, meaning that you will be consistently receiving feedback on your methodology, time allocation, implementation of knowledge, and solution paths as you progress through your GMAT preparation. This ongoing back and forth communication will allow you to identify your weak spots in self-prep as well, and revisit appropriate material to deepen your understanding of less comfortable concepts.

3. Learning at your own pace, and then speeding it up

Timing is the most crucial aspect of the GMAT that you need to master to achieve a great score. Naturally, everyone excels at tackling some problems and needs more time to solve others. Tutoring can hone your timing decisions and your tutor can create a customized plan for timing allocation across a range of problems depending upon your relative strengths and weaknesses.

Studying with a private GMAT tutor will also allow you to spend the right amount of time on each aspect of the exam according to your scoring needs. This lets you avoid inefficiencies and master only those techniques that will be most useful to you in order to fulfil your potential.

4. Developing specific skill sets to tackle each section of the GMAT

The GMAT test is a complex exam designed not to test high school knowledge, but rather core character traits like adaptability, time management, critical thinking, logical reasoning, and multitasking. You cannot achieve a high GMAT score if there is a significant difference between your performance in each section of the exam. A private GMAT tutor can give you the best insights on how to build, manage, and combine the different skills needed to get a great end-result and achieve parity between your verbal and quantitative scores.

5. Realizing better use of your time

Flexibility and accessibility of learning is key to maximizing your potential. One-on-one GMAT tutoring is:

  • Usually offered online. This means that you can schedule sessions at the most convenient time depending only on your flexibility. You can have lessons in your breaks from work, gaps between classes, during daily commutes, during holidays, in the park, etc.
  • Available at any time. This is not the case with group GMAT tutoring as classes are scheduled depending on the instructor. Apex works globally, and has tutoring available in every time zone around the globe. Private GMAT tutoring should be designed to meet your lifestyle requirements and you should aim to schedule sessions when you are most productive. A technique that the best GMAT instructors adopt is to schedule sessions at a time of the day when you are supposed to sit your actual exam. This can help you simulate conditions similar to those on test day and give you important insights on how to maximize your productivity at that specific time frame.
  • Offered with different options depending on duration and material covered in the program. Whether you are a beginner or someone who already has a strong understanding of the GMAT, you can choose a specifically designed GMAT curriculum depending on what you strive to achieve. This is reflected in the amount of hours you are going to spend with an instructor and in the price of the service. At Apex we offer a complimentary first call to help you determine what course of action will be the most suitable for you depending on your current level of preparation and your GMAT aspirations.

6. Understanding where you excel and what you struggle with most

If you are aiming for an elite GMAT score, you’ll need to leverage your strengths and recognize your weaknesses. Understanding the meaning behind each question, its structure and underlying testing purpose, and the methodologies the test writers use to construct the problems is essential for success. The best one-on-one GMAT tutors are aware of the subtleties of the exam and can not only guide you around them, but teach you how to leverage these subtleties for high level insights into the hardest 750+ problems. This will predispose you to uncovering features of the test that most preppers have never even considered.

7. Utilizing learning aids

Finding and gaining access to challenging GMAT problems, authentic and reliable practice tests / mock exams, and appropriate study tools can take ages to hunt down (and cost a fortune). One-on-one GMAT tutoring allows you to refocus your valuable time as experienced instructors will already have compiled a solid database of resources and questions and show you the ones that are most relevant to your success at your current level. That way, your instructor, and not you, will spend the time filtering them according to your needs and present the ones that will have the greatest positive impact on your GMAT preparation.

8. The expertise and professional mentorship of a private GMAT tutor

Working with an expert GMAT tutor who has scored well into the top 1%, and who knows the exam inside and out will help you accelerate your learning and move the needle of your progress in ways you only read about on GMAT blogs. Experienced instructors are trained to teach you how to overcome the different GMAT scoring plateaus and meet your personal target. The goal of great tutors is not only to show you how to answer a question correctly, but also to help you extract a methodology that can be continuously applied to other questions across the GMAT, and to problems beyond.

Apex’s tutors focus on teaching the higher order strategies that are necessary for the achievement of a 700+ score and bringing out your optimal performance. Enlisting the help of a one-on-one GMAT instructor is recommended for those who are short on time or those who already have a solid understanding of the exam and are scoring well (low to mid-600’s), but are looking to gain those extra points that will make them get into their dream MBA program and lay the groundwork for a challenging, engaging, and lucrative career.

Should you include your GMAT score on your resume?

A lot of our clients ask if having a good GMAT score can help you on a job search. The truth is that for some jobs it can be immensely useful. However, other jobs might not even take a look at it. Ultimately, it’s up to the HR departments of your potential employer. Still, there are some rules of thumb to follow. 

A Really Strong Score

Let me first begin by saying that the only time you should list the GMAT on resume is if it’s a really strong score. We’re talking 700 or above. There’s no sense talking about a middling or even middling-good GMAT score if you run the risk of having someone ask: “Well why didn’t you score higher?” Really, the bar is about 700. 

There are a lot of industries that really value it if you put your GMAT on resume and those are going to largely parallel those that value the MBA. Finance, banking, and consulting firms will generally respond favorably to a GMAT score and one of the things to understand about why this is is to understand what the GMAT is and how it factors into a hiring decision. 

GMAT As a Signal

The GMAT’s what’s called a psychometric exam and much like other standardized tests, whether it’s the SAT, the ACT, GRE, LSAT, these tests not just what you know but to varying degrees, how you think and many of the top consulting shops have HR departments that have their own in-house tests. So the GMAT serves as a good proxy for those and signals that you will likely thrive and do well in the testing environment that, let’s say, McKinsey might place you in. 

Understand that a strong GMAT score on a resume immediately says to the recruiter, that you can handle a certain amount of intellectual rigor and then you have a certain amount of liability to the way you think. That’s the value of a GMAT score on a resume, aside from the fact, of course, that it compares you to your peers favorably. 

Include Your GMAT Score Where Necessary

So, as you’re hunting for jobs, whether it’s post-MBA or whether you just took the GMAT and decided not to go to business school or got an alternative degree, think about listing your GMAT on resume and think about it as a talking point for how you overcame an obstacle or in a way that might be complementary to the profile or the narrative that you’re trying to present to a particular hiring manager. I hope this helps and if you have any questions don’t hesitate to contact us!

When To Study For The GMAT?

If you are reading this at any time other than the morning, you’re probably not getting your optimal yield out of your self-prep time. Let’s talk about how the time that you spend preparing and the relative yield you get from that time can change. 

Time of Day

Most of us have good times and bad times of the day, and that’s tied in very deeply to our biology and our circadian rhythm. Most people are at their sharpest mid-morning. However, if you’re constantly sleep-deprived this might change. In fact, it might never be optimal. 

In order to get the best out of your self-prep time, you need to be capitalizing on the best times of the day to study. This also means to not overdo it. Don’t force yourself into studying when you’re not up for it. If you’ve worked a 10-hour day, whether on a desk, on the street, or doing big projects and traveling to a client as a consultant, your study time is very limited and studying when you’re exhausted is not only going to be low-yield but it’s also going to take a lot out of you so that you’re not able to capture those high-yield times.

Small Increments of Study Time

Instead, try self-prepping in smaller units throughout the day. Particularly in those times when your sharpest. If you can grab 15 minutes at 10 o’clock in the morning, even if it’s a bathroom break or 20 minutes on your commute, do so. Those are really good times to prep. Doing little increments throughout the day increases your contact density but also decreases the burden from your daily schedule. 

Many of you out are working crazy jobs, balancing a social life, family obligations, and the GMAT can take over. Particularly if you’re spending 10, 20, 30 hours a week self-prepping. If you are, you’re spending too much time. You’re better off getting stronger results out of smaller increments of high-yield time rather than killing yourself and studying 3-6 hours at a time on the weekends or in the evenings. 

Quality Over Quantity

When you prepare and how you prepare is much more important than how much time you prepare. Be mindful of when you’re sharpest during the day and to take at least a portion of that time and devote it to your GMAT prep, because what you’re ultimately doing is personal development. 

As much as you might be devoted to a job, it’s not going to be there forever. Your personal growth, a high GMAT score, and also getting into the next step of your career or the next step of your education. That should be your priority and you need to make sure you balance that with your other obligations. 

When To Study For The GMAT?

So remember: incremental short study breaks, or in other words, breaks from everything else you’re doing to study, increasing your contact density. If you’re tired, and this is probably the biggest takeaway, don’t force yourself to study because you’re just spinning your wheels. You are not going to get a good yield out of it. You’re better off putting on Netflix, taking a nap, spending time with loved ones, going out with friends, and getting yourself on an even keel. So that the 60 to 90 minutes a day that you can devote to GMAT is the best 60 and 90 minutes you can give it. Try to get some rest cause I know 90% of you are reading this while tired. Best of luck on your GMAT Prep Journey!

How Can Private Tutoring Help You Score 700+ on the GMAT?

By: Apex GMAT
Contributor: Irena Georgieva
Date: 14th July, 2020

Achieving a 700+ score on the GMAT is not a simple task – it requires significant preparation, excellent organization, and continuous motivation to learn. Studying for an exam can be overwhelming, especially when there is no one by your side to keep you motivated. Perhaps you’re struggling with quant problems or you’re not sure how to apply the strategies that you have learned. Well, don’t worry… This is where private GMAT tutoring comes into play.

Here are the top 5 reasons you should start working with a tutor in order to ace the GMAT.

       Index:

1.     Individualized Learning Experience

Although the GMAT is a standardized exam, there is no one size fits all approach to success. While some students favor graphical solution paths, others are more analytical or methodical in their approach to answering GMAT questions. Some struggle with geometry, others with algebra, yet others with critical reasoning. There are learners who have excellent writing skills, while others, particularly ESL students, require practice to achieve a good score on the analytical writing assessment. The existence of these differences indicates that there is not only a singular path to studying for such a nuanced exam and that preparation should be customized to maximize one’s strengths and abilities.

Unlike classroom teaching where the teacher rarely deviates from the prescribed syllabus, a competent private tutor will tailor your learning plan based on the knowledge and skills you currently possess and their expertise. By identifying your learning style and framing your entire prep program around it, a skilled GMAT tutor will ensure that you are not only progressing through your prep but enjoying it as well.

What’s more, a perceptive private GMAT tutor will also focus your attention on the areas where you experience difficulties or need improvement, especially those areas that you can’t see for yourself. Due to this guidance and direction, you will be able to spend more time on improving, and less time repeating the same mistakes or going over content that you’ve already mastered. You’ll develop new skills that were previously lacking and adopt more favorable methods to solve difficult problems. Additionally, you will learn how to organize your time more effectively which is essential for you on the exam.

2.     Personalized Attention

Although classroom teaching can prove beneficial for mastering the fundamental knowledge needed for higher level approaches, one disadvantage of learning with others is the lack of personalized attention and focus on the lowest common denominator type construal of the concepts being taught. Teachers in any classroom cannot pay attention to all of their students’ needs, especially those who struggle differently than most, or who have higher goals than their classmates. While one student might be struggling with the clustering principle that defines standard deviation as it applies to comparing different sets, another might require a refresh on calculating variance and how the underlying concept operates. Whatever your specific case may be, the help of a private tutor can address it.

By working with a top-notch tutor outside of the classroom, you’ll be able to rapidly progress and draw on personalized mental models to confidently approach GMAT problems of the highest complexity. A skilled GMAT tutor will not only help you acquire new knowledge but s/he is also going to teach you valuable meta-strategies that can be useful for you when you study for the exam. At Apex we focus on solution paths, problem forming, and many other innovative techniques that make for high-yield self preparation, and top level scores.

Moreover, a highly qualified private tutor will have a team behind him/her and copious amounts of materials and drills, while drawing upon a flexible curriculum so that your preparation can be as personalized and efficient as possible and result in the score you are striving to achieve. You shouldn’t be afraid to speak openly with your GMAT tutor about any concerns you have regarding your preparation, and your tutor should always be open to your feedback and input, rather than trying to “run the show”. Recall that the purpose of engaging a tutor is not only the acquisition of knowledge but also the attention and support you will be given.

3.     Improved Confidence

Working with a proficient private tutor will definitely boost your confidence, and confidence is essential to exemplary GMAT performance. After a few sessions, you should expect to see how much your tutor has helped you learn and adopt fresh skills and additional perspective – about the GMAT and about yourself as a test taker  – and address the problems you thought impossible just a few short weeks prior. Almost imperceptibly you will become more proficient in your execution and more sensitive to the different ways the GMAT modulates complexity and delivers hints about the most viable and efficient solution paths (here at Apex we call these “Test Reads”). Thorough preparation will marginalize your fear of failure and help you combat latent (or not so latent) test anxiety so that you can manifest the high expectations that you’ve likely set at the outset of this process.

In addition, a capable private tutor will ensure that you address your anxiety about the exam in a healthy way. Aside from designing a study plan customized to your learning style, your GMAT tutor will focus on other salient, but less popular factors that affect GMAT performance; the amount of sleep you get, and overstudying, to name just two. While you might not have considered these factors, or believe them to be unimportant, they drastically influence productivity and affect test day performance. That is why an experienced GMAT tutor will do everything s/he can to make you ready, and make you feel ready, for your exam.

4.     Greater Motivation

Constant preparation can be exhausting and without the proper support and encouragement, it’s normal to lose your motivation along the way. A tutor, however, can provide that motivation and understanding of what you’re going through – something well meaning friends and family cannot – so that your goals become reality.

Apart from ensuring your efficient preparation for the GMAT, a personal GMAT tutor will also be your greatest mentor, motivator, and cheerleader. S/he will be the person who will check in, see how you’re doing midweek, and encourage you the most because he/she will be personally invested in you and will have a professional stake in the outcome of your preparation. The best tutors take their clients’ successes personally, and this informs their attentiveness and personal pride. The faith that your tutor has in you should inspire you so that you can achieve your dream score and satisfy your collective expectations. Thus, you will be even more motivated than before and you will perceive the exam as an opportunity to demonstrate all the novel skills you have developed and trained throughout your preparation.

5.     Higher GMAT Score

Last, but certainly not least, preparation with the help of a private tutor will result in a higher score on test day when compared to classroom learning or self-preparation alone or in combination. As we have already mentioned, lessons from a devoted private tutor will provide you with an individualized learning experience and more personalized attention which will lead to an increase in your confidence and motivation for the exam. Finally, you will learn more than just GMAT strategies from your tutor. You will learn critical and creative thinking skills, heuristics, mental models, and other thinking tools that will help you make the most of all future learning opportunities. The best tutors, like the ones here at Apex, teach you how to better learn, and become mentors and trusted advisors as you progress through your MBA and further career.

Final Notes 

To sum things up: private GMAT tutoring can be expensive but the value it will deliver will be more than worth the money. The best tutoring stays with you and will add color and perspective to your future learning, whether in your MBA, on the job, or as you progress through your career. If you want to embark on your GMAT journey with a private tutor, make sure you:

  • speak to several instructors at first. Apex offers a complimentary consultation call and you can schedule one HERE.
  • learn more about how to select a GMAT tutor.
  • hear the opinions of others who have already tried private GMAT tutoring HERE.

8 GMAT Test Strategies To Help Boost Your Score

By: Apex GMAT
Contributor: Ivan Minchev
Date: 9th July, 2020

More than 250,000 students take the GMAT every year as a requirement to get into the thousands of different MBA, EMBA, MFin, MAcct and Management PhD programs worldwide. However, due to the complexity of the exam as well as its adaptive difficulty only the top 12% of test-takers manage to score 700 or above. Here are 8 GMAT test strategies you can utilize to achieve a higher score on the exam, no matter where you currently are on your GMAT preparation journey.

1. Adopting the proper mindset

Perspective  is everything. It is very important to understand that even though getting in the top 10% of test-takers might seem like a spectacular achievement (and don’t get me wrong, it certainly is) setting your goals on a certain score tends to be counterproductive. Instead, focus on attaining specific skills, knowledge, and command, and the score will follow. Goals lead to expectations and fear of failure, and fear of failure in turn results in stress, which can greatly hinder performance.

2. Overcoming stress!

Stress and fear can greatly influence your results, but there are ways to manage these very normal responses to a high stakes situation. One of the ways to reduce stress and boost your confidence is by beginning your preparation process as early as possible – ideally 90-120 days before the exam. This provides enough time to fully grasp the complexities of the exam, and more importantly internalize a new set of skills to handle that complexity.

A test taker’s greatest enemy is test anxiety. Understand that anxiety happens to everyone. What sets top performers apart is how they handle that anxiety, and how they direct it back into their performance. Many people use a variety of relaxation techniques for dealing with test anxiety. The most common and easy to use method is to practice deep and controlled breathing in combination with visualization techniques. 

3. For exam day…

Are you a coffee drinker? Surprisingly, caffeine can really help your performance on test day. Caffeine is a powerful nootropic that will help keep your senses sharp and will also boost the oxygenated blood flow to your brain, subsequently enhancing your performance. For more info on how coffee affects your performance click here. 

Remember how we said that it’s important to begin your exam prep early? This “early bird” attitude can be applied in more ways than one. What this implies is that you must (not might, not should) prepare your GMAT Test Day Survival Kit on the previous day and not leave this for the last moment. Everyone has waited for the last minute to do something, and chances are everyone has left something crucial behind. With the GMAT being such an important exam such situations should be avoided as much as possible. Try having a mock exam day. Map out the whole test day and practice it as if it were real, including your trip to the testing center. This will help you normalize the process and alleviate anxiety on test day.

4. Value your time and manage it efficiently!

Since the GMAT is a timed exam one’s planning and strategic skills are put to the test as they have to come up with an efficient time management strategy.

Use mental math tools whenever possible and also try getting used to reading and analyzing charts, graphs and tables efficiently for the Integrated Reasoning section. 

Once you’re further along in your preparation and have mastered seeing multiple solution paths before engaging any of them, familiarize yourself with common problems, and built up test reading and perspective skills, then you can begin dedicating yourself to timed sets: working on a cluster of 10 consecutive questions for each section of the exam when on the clock. This helps you calibrate your timing decisions and more readily notice when they require adjustment.

Remember, just because the GMAT is a timed exam, this doesn’t mean we must learn under a time constraint. Like good cooking, good learning takes time. Give yourself sufficient time to learn, while also making sure the learning time is spent as productively as possible.

5. The Integrated Reasoning section

Dealing with 12 multi-part questions in 30 minutes means that you’re going to be overwhelmed with information, and you won’t have much time to spare. Sorting through large amounts of data and understanding it in a timely manner is key to getting through this section.

A good way to rapidly identify information needed to solve a problem is knowing what to look for. Read the problems carefully (and this applies to all sections) and proactively determine what you want out of the information or solution path. This way, you will sift out most unnecessary information in advance, saving plenty of time along the way. However, this does NOT mean to ignore the text written around the tables/graphs/charts.

6. The Analytical Writing section 

Failing to plan is planning to fail! Always plan your essay! Set aside 4-5 minutes to plan what you are going to write and how you are going to structure your essay. 

Create an essay template in advance! There are many ways you can go about making one but usually, the more you practice your essay writing skills the more used to a specific writing style you are going to get ultimately resulting in your own template.

7. Ask for help

There is nothing embarrassing about asking for help, especially when it comes to an exam that is so vital to one’s future. There are numerous GMAT forums and courses on the web, where you can ask and get help from people who have already taken it.

However, if you would prefer a more personal and individualized approach you could consider hiring a private tutor. The benefit of not preparing alone but hiring a tutor is that it allows for direct feedback on what are an individual’s strengths and what needs improvement, while also receiving advice on how to achieve those improvements. As a result, when the exam day comes you will not only be well prepared but will also know it, having built up confidence in your abilities.

8. Practice, practice, practice!

No doubt you’re familiar with the phrase “practice makes perfect.” There is a reason why this is such a popular saying: it’s true! Not all practice is equal, though. Varied practice that aims at building on existing skills and knowledge is much more high yielding than repetition. No matter how clever you are, no matter how good of a student you’ve been or how proficient in math you are if you do not put enough time and effort in your prep you are not likely to be happy with the end result. Even the top tutors and courses out there won’t be able to help you out if you don’t give your best. So remember, don’t just go through the motions, but practice by constantly looking at the same problems and concepts in new ways, and trying to use them in novel situations, and you’ll find your GMAT prep vastly accelerated.

That was the list of 8 strategies to help you score high on the GMAT. Keep in mind that what works for one person will not necessarily work for another as everybody learns differently. It is only through practice and proactive learning that you will be able to find what are the best methods for your success.

GMAT Problem – Speed Distance Problem

Speed and distance problems are among the most complained about problems on the GMAT. Numerous clients come to us and say they have difficulty with speed and distance problems, word problems, or work rate problems. So we’re going to look at a particularly difficult one and see just how easy it can be with the right approach.

The Two Cars Problem

In this problem we have two cars – car ‘A’ and ‘B’. Car ‘A’ begins 20 miles behind car ‘B’ and needs to catch up. Our immediate DSM (Default Solving Mechanism) is to dive in and create an equation for this and that’s exactly what we don’t want to do.

These types of problems are notorious for being algebraically complex, while conceptually simple. If you hold on to the algebra, rather than getting rid of it, you’re going to have a hard time.

Solution Paths

In this problem we’re going to build up solution paths. We’re gonna skip the algebra entirely. We’re going to take a look at an iterative way to get to the answer and then do a conceptual scenario, where we literally put ourselves in the driver’s seat to understand how this problem works. So if we want to take the iterative process we can simply drive the process hour-by-hour until we get to the answer.

Iterative solution path

We can imagine this on a number line or just do it in a chart with numbers. ‘A’ starts 20 miles behind ‘B’ so let’s say ‘A’ starts at mile marker zero. ‘B’ starts at 20. After one hour ‘A’ is at 58, ‘B’ is at 70 and the differential is now -12 and not -20. After the second hour ‘A’ is at 116, ‘B’ is at 120. ‘A’ is just four behind ‘B’. After the third hour ‘A’ has caught up! Now it’s 4 miles ahead. At the fourth hour it’s not only caught up but it’s actually +12, so we’ve gone too far. We can see that the correct answer is between three and four and our answer is three and a half.

Now let’s take a look at this at a higher level. If we take a look at what we’ve just done we can notice a pattern with the catching up: -20 to -12 to -4 to +4. We’re catching up by 8 miles per hour. And if you’re self-prepping and don’t know what to do with this information, this is exactly the pattern that you want to hinge on in order to find a better solution path.

You can also observe (and this is how you want to do it on the exam) that if ‘A’ is going 8 miles an hour faster than ‘B’, then it’s catching up by 8 miles per hour. What we care about here is the rate of catching up, not the actual speed. The 50 and 58 are no different than 20 and 28 or a million and a million and eight. That is, the speed doesn’t matter. Only the relative distance between the cars and that it changes at 8 miles per hour.

Now the question becomes starkly simple. We want to catch up 20 miles and then exceed 8 miles, so we want to have a 28 mile shift and we’re doing so at 8 miles an hour. 28 divided by 8 is 3.5.

Conceptual scenario solution path

You might ask yourself what to do if you are unable to see those details. The hallmark of good scenarios is making them personal. Imagine you’re driving and your friend is in the car in front of you. He’s 20 miles away. You guys are both driving and you’re trying to catch up. If you drive at the same speed as him you’re never going to get there. If you drive one mile per hour faster than him you’ll catch up by a mile each hour. It would take you 20 hours to catch up. This framework of imagining yourself driving and your friend in the other car, or even two people walking down the street, is all it takes to demystify this problem. Make it personal and the scenarios will take you there.

Snack Shop GMAT Problem

The Snack shop GMAT problem is an average or a mean problem. A characteristic of many average problems is that one big takeaway right at the outset is that the answer choices are clustered tightly together. We want to refrain from making any calculations.

The problem is below:

snack shop problem

Selecting A Solution Path

If they’re looking for a level of precision, the estimation solution path isn’t available to us. If we dive into the problem, right from the first sentence we have sort of a conclusion that we can create via either a graphic or accounting solution path.

If you were the business owner immediately you’d say to yourself: Well for 10 days and an average of $400 a day I made $4000. 

This is how we want to think about averages. Many times they’ll tell us a parameter about a length of time or over a certain universe of instances and here we want to treat them all as equal.

Solving the Problem

It doesn’t matter if one day we made 420 and another day we made 380. We can treat them in aggregate as all equal and start out with that assumption. That’s a very useful assumption to make on average problems. So, we start out knowing that we made 4,000. 

What I want us to do is do a little pivot and notice from a running count standpoint how much above or below we are on a given day. So we’re told that for the first six days we averaged $360 which means each of those six days we’re short $40 from our average. That means in aggregate we’re short $240. 6 days times $40 –  and this has to be made up in the last 4 days.

Notice how we’re driving this problem with the story rather than with an equation. In the last four days we need to outperform our 400 by 240. 240 divided by 4 is 60. 60 on top of the 400 target 

that we already have is 460. Therefore, our answer is D.

Graphical Solution Path

If we are more comfortable with graphic solution paths, imagine this in terms of 10 bars each representing $400. Lowering six of those bars down by 40 and taking the amount that we push those first six down and distributing it among the last four bars gives us our $460 total per day.

GMAT Scoring – Demystified

One of the most common questions asked by those who are new to the GMAT is how exactly does the computer adaptive test or CAT work? The long and short of it is that if you get a problem correct, they give you a harder one, if you get a problem incorrect, they give you an easier one. By doing this the GMAT is able to bounce up and down and calibrate to your skill level.

Should You Spend more time on the first 10 questions?

A few things come out of this including questions about how to spend your time. Whether certain questions are weighted more than others, whether your timing, that is the amount of time you spend on a problem factors into the score.

To start, there’s a common misconception that you should spend more time on the first 10 questions because they tend to adjust your level for the computer adaptive test at a greater rate. While that’s true in the sense that the computer adapted model on the GMAT does influence it more at the outset, whether you should spend more time is actually a more complex question because generally the GMAT is going to give you problems that are about average and build up or down from that average.

Planning To Score An Elite GMAT Score

If you’re planning on performing at a top level, at an elite level, if your goal is 700 or even 600, you need to assume that those early problems that are average level problems you’re going to do well and in a timely manner anyway.

That is spending extra time to ensure you get them correct is a grandiose version of spending extra time to make sure that you’re getting two plus two correct. You wouldn’t check that because you’re confident enough in your skills and if you’re in the GMAT and you’re getting ready to shoot for a 700 you should already be confident enough in your skills not to have to spend extra time on average level problems. To take these problems on a problem-by-problem basis rather than with blanket statements.

Does The Test keep Track of Other Information?

A common question is whether or not the test keeps track of the type of problems you do. This can refer to:

    • subject matter
    • problem solving versus data sufficiency 
    • reading comprehension versus critical reasoning versus sentence correction

However, we can still go about it with the core rule: if you get it right you’re going to see something more challenging, get it wrong, less challenging. We tend to believe that they don’t keep a great track of that but really rely upon the bouncing up and down to calibrate you to your average performance level. You don’t want to sweat any single problem or worry about any single problem type in regards to the Computer Adaptive Test.

Certainly,  sometimes you’ll know that certain types of problems require more or less attention from you or that you make common errors on those problems. However, that’s not a CAT thing, that’s just a general GMAT thing. 

You are penalized for spending too much time on a problem but not in the way you think.

The other big question we hear a lot is whether or not the amount of time you take on a problem factors into the score. The answer here is subtle, it’s yes and no. No in the sense that the GMAT scoring algorithm does not track the amount of time that you spend on a problem. But, yes in the sense that the more time you spend on problems the less time you have for other problems. In particular, if you’re scoring above average, you’re on this ascendant curve so that the difficult problems at the end require more time than the less challenging problems at the beginning.

Therefore, if the GMAT kept track of your time and penalized you for spending longer on problems they would actually be penalizing you twice and this gets us into our timing decisions and the trade-off between time and score.

Time and Score Trade-off

When you’re armed with confidence and knowledge about how something works you don’t have to worry about how it works or how what you’re doing affects how it works and you can focus on the task at hand. 

The more that you can offload the burden of worrying about the scoring and the mechanisms by which the GMAT measures you, the more success you will find. As always, I hope this helps and keep prepping!

The Effects of Coffee on GMAT Performance

Let’s talk about caffeine and the effect of coffee on GMAT performance. Caffeine is a neuro-stimulant. Drinking coffee or tea while you prep and particularly being appropriately caffeinated when your test is a decided advantage. Caffeine is a nootropic, which means it helps you be smarter. It also helps your cognitive abilities become enhanced due to increased blood flow and oxygen flow to the brain.

Find Your Right Amount

It’s important to understand how much caffeine helps, not just to wake you up in the morning. More than that, it’s about how much caffeine is needed to get you to that a really nice steady state of alert focus-ness (where you’re making up words like alert focus-ness) where you kind of feel on top of the world and you have that gentle energy.

You want to understand exactly how much caffeine your body can take because there’s nothing worse than being over caffeinated, jittery and anxiety ridden on the exam. But if you calibrate it properly caffeine is an important part of your GMAT diet.
