Why is your GMAT Score Important for Prospective Jobs?

Taking the GMAT and getting a 700+ score is not only going to help you pursue your MBA career, it will also facilitate additional professional benefits. Indeed, the GMAT requires far more skills than just the math or verbal skills that are tested, and success can be evidence of an array of capabilities. Read on to find out what GMAT score use in employment is and why more employers are taking candidates’ GMAT scores into account in hiring decisions.

Of course, a high GMAT score primarily makes one stand out from other job applicants. Moreover, it is also a clear and objective indicator of your integrated reasoning abilities, as well as your analytical, verbal, and quantitative reasoning skills. Particularly for those interested in applying for finance, investment, or business-related employment, an excellent GMAT score can be proof of expertise in the aforementioned categories. 

At the surface level, a high score in the quant section demonstrates that a candidate can solve and interpret numerical problems. More significantly, it also implies that the applicant can be trusted with complex calculations, extensive financial reports, and other major related tasks. Furthermore, a candidate’s integrated reasoning skills will be seen to be of great professional value, especially when working with a large amount of data from multiple sources. Extrapolating the right takeaways and decision-making points from this wide array of data is a skill highly sought after by employers.  

The GMAT’s testing of analytical writing and verbal reasoning skills have implications for a candidate’s professional capabilities. Scores in these sections speak to the applicant’s capacity for critical thinking as well as how clearly and precisely they can express their ideas in written form.

Ultimately, the GMAT score helps employers select their hires based on information gleaned from standardized testing, and not just personal characteristics or experience. This allows for a selection process that is much more comprehensive. 

Since the GMAT is a requirement for MBA admission, a high score also indicates that the candidate has been admitted to a prestigious and academically rigorous university. Potential employers perceive such individuals as having a high-quality education from top-notch professors. Many of whom have worked in their industry. 

Finally, a candidate with a high GMAT score is also better placed to perform well during a job interview than someone who has never prepared for such a test. By putting his/her critical thinking and verbal reasoning skills into practice, a job candidate with a 700+ score is more likely to excel at answering questions that require the application of analytical and logical skills. Moreover, having taken the GMAT, prospective hires enjoy minimal interview anxiety or stress, because they were trained to manage such issues while preparing for the test. Additionally, they may be exempt from taking company interview tasks due to their performance on the GMAT. 

For all these reasons, employers will always value individuals with high GMAT scores, giving them preference over the job seekers with low or no GMAT scores. For more information regarding the GMAT Scoring, GMAT Scoring Demystified is a very insightful article to read.

Combinations with Restrictions

By: Rich Zwelling, Apex GMAT Instructor
Date: 4th March, 2021

In our previous post, we discussed how GMAT combinatorics problems can involve subtracting out restrictions. However, we discussed only PERMUTATIONS and not COMBINATIONS.

Today, we’ll take a look at how the same technique can be applied to COMBINATION problems. This may be a bit more complicated, as you’ll have to use the formula for combinations, but the approach will be the same.

Let’s start with a basic example. Suppose I were to give you the following problem:

The board of a large oil company is tasked with selecting a committee of three people to head a certain project for the following year. It has a list of ten applicants to choose from. How many potential committees are possible?

This is a straightforward combination problem. (And we know it’s a COMBINATION situation because we do not care about the order in which the three people appear. Even if we shift the order, the same three people will still comprise the same committee.)

We would simply use the combination math discussed in our Intro to Combination Math post:

 10C3 =       ————-
                     3! (10-3!)


3! (7!)





= 120 Combinations 

However, what if we shifted the problem slightly to look like the following? (As always, give the problem a shot before reading on…):

The board of a large oil company is tasked with selecting a committee of three people to head a certain project for the following year. It has a list of ten applicants to choose from, three of whom are women and the remainder of whom are men. How many potential committees are possible if the committee must contain at least one woman?

A) 60
B) 75
C) 85
D) 90
E) 95

In this case, there’s a very important SIGNAL. The language “at least one” is a huge giveaway. This means there could be 1 woman, 2 women, or 3 women which means we would have to examine three separate cases. That’s a lot of busy work. 

But as we discussed in the previous post, why not instead look at what we don’t want and subtract it from the total? In this case, that would be the case of 0 women. Then, we could subtract that from the total number of combinations without restrictions. This would leave behind the cases we do want (i.e. all the cases involving at least one woman). 

We already discussed what happens without restrictions: There are 10 people to choose from, and we’re selecting a subgroup of 3 people, leading to 10C3  or 120 combinations possible. 

But how do we consider the combinations we don’t want? Well, we want to eliminate every combination that involves 0 women. In other words, we want to eliminate every possible committee of three people that involves all men. So how do we find that?

Well, there are seven men to choose from, and since we are choosing a subgroup of 3, we can simply use 7C3 to find the number of committees involving all men:

7C3 =       ————-
                 3! (7-3!)


3! (4!)



= 7*5 = 35 Combinations involving all men

So, out of the 120 committees available, 35 of them involve all men. That means 120-35 = 85 involve at least one woman. The correct answer is C. 

Next time, we’ll return to probability and talk about how the principle of subtracting out elements that we don’t want can aid us on certain questions. Then we’ll dovetail the two and talk about how probability and combinatorics can show up simultaneously on certain questions.

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.
