## GMAT Confidence

Mike Diamond, Head of instruction and Jaymes Kine one of the lead instructors here are going to talk about some of the questions that we’ve gotten on our social media platforms.

We asked for you guys to give us some questions you have asked the questions and I guess kind of talked ourselves into a corner because now we have to answer them. Do you have the answers? I have the answer guide!

#### Prep Materials

What materials to use? But I want to talk especially about the quality materials out there. There’s a wide variety of materials. Wide variety of quality but even the good materials in terms of the problems often do a great disservice to our clients by saying this is how you do it.

You look in the back and you see this especially, it’s more apparent with the quantitative. Here’s all the algebra you need to do, and so many times it’s not about the answer, it’s about thinking about other solution paths and getting around the answer. Yeah, and this is actually something that happens a lot, it’s mainly one of the major pitfalls for self-prep.

When you’re studying on your own we read through the official guide or whatever books you may have. By the way, we recommend always getting the official guide, other books to supplement are great, but at least the official guide.

We have our own materials that we would we would recommend obviously, but let’s go to the official guide on the answers there. When people are self-prepping they will go through the official guide, then they’ll be reading the official answers which they start with here’s the algebra problem and work you all the way through every algebraic step.

#### GMAT Confidence

I don’t know if you guys can tell we haven’t rehearsed and this is actually a GMAT moment. Yeah, we maybe should have rehearsed, you know failing to plan is planning to fail I think is what we say. Yes and no though, but we have all the answers.

We don’t need to go over the answers in advance we don’t need a script because we live and breathe the GMAT, this is all we do. And in that way this is a strong parallel for the GMAT. When you’re sitting the exam you don’t need to know the answers in advance ABCD whatever. If you have the tools and the knowledge, the experience, the expertise, then the answers are going to flow. And all that I think adds up to GMAT confidence to know you can go into that test and you can take it right.

Now we may be over confident here but it’s something we’re working on. But being confident when you get to the test is definitely key. And it’s often a characteristic of really high achieving test takers. To be sure none of our instructors went to the test saying, “Oh, I’m nervous I’m not going to do well,” and when we take follow-up tests from time to time that’s that’s not a question.

That’s characteristic of just about everyone I’ve met, clients, instructors, whatever that have scored above that 720/730 mark.

I think irrational confidence is probably my best my best characteristic as a test taker. That’s your best characteristic overall! Oh, thanks man!

## Quant Versus Verbal

It’s time for quant versus verbal, one of the most common questions we get. Where should I start?

#### Quant

It won’t surprise our lovely viewers that it all depends on the person, but let’s talk in some generalizations. One thing you might be surprised by, maybe not so surprised to learn, is that a distinct majority of the people we work with come to us for quantitative help versus verbal help.

At least that’s what they state upfront. Many of them end up only getting quant anyhow but a lot of people state that they only need quant and then they end up needing verbal help as well. Once your quant outstrips your verbal you want to bring them up to parity because that’s highly rewarded by the scoring algorithm.

We talk, we read, we write, we live, we’re immersed in a world of language, a verbal world. Where even math professors only math a few hours a day. Okay yeah there is a verb – to math! This is not a GMAT word but it’s an Apex word because we math frequently. Yes!

#### Fluency

So the issue there is fluency. If you’re already fluent in English, all the lessons you need to learn are much more easily attainable. Whereas with quantitative concepts even ones you think you know, often there’s more context. So you need a longer time period and more contact density with them in order to absorb all the stuff you need to then be flexible with them the same way you’re likely already flexible with the English language.

#### Verbal

A big part of that is that the verbal section is the verbal section but the math section is math in English. They’re not just equations. They’re not just giving you specific mathematics problems per se. They are giving you math problems wrapped up in words.

That goes both ways, there are quantitative problems particularly on the critical reasoning and a lot of times these aren’t: here are some numbers; figure it out. Rather, the cost-of-living index is growing more quickly than inflation, more than pensions or something like that. Where you have some sort of abstract inequality buried in a property – they require mathematical reasoning.

That’s how it goes, so anyway there’s a lot of overlap on the GMAT but especially on the quantitative side, a lot of the difficulty is puzzling out what you need to answer, not doing the equation but you’re saying: what that hell is this asking me for?

#### Non-Native English Speakers

This is something else that we feel like a lot of the other test prep factories don’t really do a good enough job in my opinion. Emphasizing what many of you may be thinking right now which is verbal help and mathematical help with verbal for non-native English speakers. There are plenty of students who come to us who are actually very good mathematicians as it were and it’s the English that they need a little bit of help with. Not as it pertains to the verbal section but actually it’s the English on the quant section that’s difficult.

Absolutely, there’s vocabulary, there’s context, but what’s really important here is that native speakers and non-native speakers pick up language differently. Even the way you learned English if you’re a non-native speaker affects how we approach working with you on the verbal. So if you’re a non-English speaker don’t be too concerned that that’s a disadvantage.

Something I’d like to point out to my students quite often is that the GMAT is actually created specifically for native English speakers and a lot of the test itself is meant to trick native English speakers. So coming at it actually from a non-native speaking background can actually help you kind of skip over all of the little traps that are set up for native speakers. So don’t despair, it’s not that you’re at a distinct disadvantage, you just have some different kind of work to do to prepare.

## Number Theory Problem Form – Wedding Guest

Today we’re going to be looking at what at first seems to be an allocation problem. But on further reflection, actually turns out to be a much simpler number theory problem.

If we take a look at the problem stem these numbers 143 and 77. They stick out to us and they stick out not just because they don’t seem to have any relative association but also because they’re sort of odd-looking numbers, they don’t look like most the numbers were used to seeing. Say 48 or 24 or 36 something easily divisible clearly breakable into factors. Here were given these two disparate numbers and we’re being asked to formulate not what the tables are made up of but how many tables there are.

###### Solving the Problem

So we look at these two numbers and we examine first the 77 because it’s a simpler lower number. 77 breaks into factors of 7 and 11. This clues us in as to what to look for out of the 143. 143 must have a factor of 7 or 11. And in fact 143 is evenly divisible by 11 and it gives us 13.

Which means that the maximum number of tables is 11. Each one has 13 people from the bride’s side and 7 people from the groom’s side. 13 plus 7 there’s 20 people at each table. Times the 11 tables is 220.

And we can back check our math, 143 plus 77 is 220. We don’t need to go that far but that might help deliver some comfort to this method. So in reality this is a very creative clever way the GMAT is asking us for a greatest common factor.

###### Graphical Solution Path

Another way to think about this is that we need an equal number of groups from the bride and groom side. The number of people on the bride’s side doesn’t have to equal the number of people on the groom’s side. We just need them broke in into the same number of equal groups. Graphically, the illustration shows us how a certain number of different sized groups combined into this common table. So 13 and 7 and we have 11 groups of each.

###### Problem Forming

This is a great problem to problem form. It will give you some additional mental math or common result experience by forcing you to figure out numbers that you can present that at first don’t look like they match but in fact do have a common factor. You’ll notice that if they had given you 16 people and 36 people finding that common factor might be easier.

So as you problem form this try and do it in a way that sort of obscures the common factor. Either try it maybe where they have multiple common factors and you tweak things like what is the greatest number what is the fewest number of tables. Or even do a perspective shift and take a look at say how many guests are represented at each table. Or on the bride’s side or on the groom’s side. Of course there are conceptual shifts to this and you can make this story about anything. Once you control the story or rather the structure of the story this problem becomes very very straightforward.

Hope this helped, I look forward to seeing you guys soon.

## Sleep Affects Your GMAT Preparation

What is the number one thing that gets in the way of GMAT performance and preparation for that matter? It’s not quantitative, it’s not verbal, it’s no problem type or rule or anything like that. In fact, it’s a good night’s sleep or more particularly, it’s consistently having a good night’s sleep.

Sleep hygiene and allowing the brain to absorb the information it’s learned in the past day, as well as prepare to absorb new information in the coming day is absolutely essential to learning any new process or skill. Yet, most professionals preparing for the GMAT are already running at a continuous sleep deficit. The best thing that you can do for yourself is to get a full eight hours of sleep every night!

###### Prioritization of Time

If you say “well I don’t have time between my work and my social life and the GMAT”, consider this: People who get a full night’s sleep are significantly healthier and happier than those who do not. So, if you don’t have enough hours in the day, re-prioritize your time. That might mean taking yourself out of the GMAT for a little while. Actually, it should make you more cognizant of all the things you’re not doing with your time. Thereby, allowing you to refocus towards the future and why you’re preparing for the GMAT.

Way too often, it’s too easy to rob Peter in order to pay Paul. That is borrow now, to pay later. When we do this with our time, we put ourselves in this downward spiral. This downward cycle where we’re focused more on the job at hand than where we’re looking to go. We see this a lot with our clients who are preparing for the GMAT.

###### Invest in Yourself

Being committed professionally is vital to success, it’s vital to growth and learning. At the same time, if you’re so committed that you’re putting in 12 or 14 hour days, every day, then maybe it’s time to revisit the resources you’re giving to your employer rather to yourself. Ultimately, the amount of time you invest in the GMAT, in yourself and your sleep is entirely up to you. Realize that the best outcomes come from prioritizing yourself, your learning and your career and leveraging them to be as productive as you possibly can at work, on the GMAT, at business school and ultimately beyond.

So turn the computer off, put on some soft music and go to bed.

## If you’re doing math on the GMAT, watch this.

I want to discuss one of the core tenents of Apex’s quantitative philosophy on the GMAT. “If you’re doing math, you’re doing something wrong.” Meaning, if you find yourself doing math, that’s a signal from the exam that you’re using a sub-optimal solution path. By math I don’t mean any calculation whatsoever, but any calculations that aren’t reasonable. That don’t come out easily, neatly and cleanly, once you’re well practiced with mental math. So it’s not that we’ll never do a calculation, but every calculation we do should be deliberate and smooth.

###### The Most Overused Solution Path

Let’s go a little deeper into this, because it’s a really important concept. Many, many people preparing for the GMAT spend way too much time worrying about the math. Being freaked out about the math and on the exam doing the math. The applied mathematical solution path is the most over used solution path on the quantitative side of the GMAT. Particularity among engineers, and with people who do a lot of self-prepping. They look to the back of the book or look to previous experience as students. And get caught up in the idea that their answer needs to be precise. This gets in the way of using our estimation solution path or other higher solution paths, which can get us to the correct answer much more quickly.

###### The GMAT isn’t Testing Your Math Skills

How do we know that math is not what the GMAT wants us to do? It’s quite simple. If the GMAT was the referendum on how well you can do mental math, then the scores would reflect your ability to do so. MBA programs at top business schools would be filled with people with extraordinary, almost savant like mental math abilities. We know this isn’t the case.

Actually, as we improve on our mental math, we get diminishing returns with it. So we see a lot of clients getting up to the 70th, 80th, or 90th percent level even, on the quantitative side of things. Then, all of a sudden they plateau; they can’t get any higher. The reason is they are so focused on the math. They are missing the bigger logical reasoning picture or the structure of quantitative problems that doesn’t rely on doing math that allows both quick and accurate solutions.

###### Key Things to Avoid

While math has its place, we want to be sure that we’re not putting it on a pedestal. And that when we’re performing computations, we’re doing so with great deliberation, intentionality, and that we have a good reason for doing any computation we’re doing. If you find yourself diving into the equation or doing a lot of processing, stop. Say “Wait a minute, there must be a better way to do this.”

Another option is that sometimes you make a basic error early on and that leads to ugly numbers and math. But you should never, never, never be multiplying decimals out to the fourth decimal. That sort of math is the true trigger, the true signal, that there’s a better way to solve the problem. When you’re self prepping, this is what you want to look for.

So by the time you get to the exam, you’re not catching yourself doing math, but you’ve already incorporated it into your process, the fact that math shouldn’t be your default.

So, remember, guys, if you’re doing math, you’re doing something wrong and you can take this one to the bank.

## Profit & Loss Problem Form

The profit and loss problem form that this problem fits into is one that has strong DSM’s into mathematics. Here we are tempted to do the math in part because that’s so easy. It’s so available to us.

This is characteristic of a mid-level arithmetic problem where there’s some shifts and shimmies but overall it’s a fairly straightforward problem that utilizes no more than the four basic operations. So on the one hand this profit and loss problem is pre-algebra or even sort of grade school math. On the other this makes the solution path much more elusive.

###### Solving the Problem Using Math

So of course we can follow the math. We can add up all the costs, five thousand plus two dollars, times twenty thousand. Then contrast that with the revenue that comes in which is 12×20,000. But then we’re left with the ugly division problem that brings us to the profit per t-shirt. This is where the GMAT sticks us.

Instead of handling this in aggregate it’s strongly preferable to handle it with a higher level solution path. Let’s take a look at a few:

###### Higher Level Solution Path: Distribution

One way to do this is to distribute the fixed cost over the cost per t-shirt. This is actually a lot easier than it seems. Twenty thousand t-shirts, five thousand dollars, five over twenty is one-quarter.

Therefore, it costs one-quarter per t-shirt in addition to the two dollars in variable cost. So twelve minus two is equal to ten dollars, minus one quarter is equal to nine dollars and seventy-five cents.

###### Higher Level Solution Path: Graphical Equalization

We can also use a graphic equalization method in order to get to the same conclusion. If the numbers were more complicated, understanding that that shift is one-quarter down. That is the fixed cost is one-quarter down.

Then we know we’re looking for something that ends in a seventy-five cents. That allows us to eliminate all the answer choices that don’t end in 0.75. Then we can use scale to determine that 9.75 is the correct answer.

###### Practice Problems

There are more complicated versions of this problem form. In particular, I’d encourage you to explore being told that the t-shirt company is breaking even. Then determining the amount of variable costs or fixed cost that’s there or even the production run. Similarly, you can be given a target profit or loss, the break-even just being the zero, so it’s a bit easier and have to reverse engineer the relationships.

Once again, this doesn’t have to be done algebraically. As you begin to appreciate the subtlety of the ratio between costs production run and total P&L all of these problems should be simplified and should be very straightforward.
