Hi All,

I've been struggling to bump up my Quant score. I started studying for the GMAT in mid August and took the official test on October 26, scoring:
35 Q
32 V
5 IR
6 ANALYTICAL WRITING

Today, I took MBA Practice test 3 and was pleased my verbal score remained relatively high, while my quant dropped 5 points compared to MBA Practice test 2. My scores are the following:

11/9/18 MBA Practice Test 2
Total: 690
46 Q
38 V
7 IR

11/21/18 MBA Practice Test 3
Total: 650
41 Q
39 V
7 IR

My biggest issue with Quant is careless mistakes. Despite reading the question several times, it seems at least half of my incorrect answers are careless mistakes. Also, there are questions that really stump me and eat away at my time where I am forced to rush toward the end of the section and not surprisingly, I get the last few questions wrong in a row, despite rather favorable topics. If anyone has any suggestions to improve my quant score to the high 40's, I would greatly appreciate the help/advice. My goal score is AT LEAST a 650. Verbal tends to be my stronger section and my strengths on the Verbal are primarily in SC and RC. CR still remains difficult for me. Thanks again!

Hi gmatconqueror2018,

You can try out the TTP course as it is phenomenal and covers the entire syllabus really well. Plus it has great reviews on GMATCLUB. I must add that if you are particularly looking to discover and improve on your weak areas in Quant; a subscription to GMATCLUB tests is the best way to do that. They are indeed phenomenal and will not only pinpoint your weak areas but also help you improve on them.

Further taking multiple mocks might help. Apart from the GMATPREP, Manhattan GMAT tests and Veritas Prep Tests in my experience have good verbal and Quant section and will certainly help you point out and improve your weak areas.

Further another advantage of taking many mocks is to build up your stamina. Apart from the GMATPREP tests, taking practice tests of any major GMATPREP company ought to do that.

Lastly I would also encourage you to purchase the latest version of OG and the Quant review for some great additional practice. Here is a link that will help you with your decision.

Hope this helps. All the best.

Hi gmatconqueror2018,

I’m glad you reached out, and I’m happy to help. You may be committing careless errors for a multitude of possible reasons, from not reading carefully to writing sloppily to making mental math mistakes. It’s also possible that your careless errors are due, in some part, to a relative lack of GMAT quant knowledge in certain areas. If you don’t know GMAT quant like the back of your hand, careless errors are likely, right? Take the following example:

14! is equal to which of the following?

(A) 87,178,291,200
(B) 88,180,293,207
(C) 89,181,294,209
(D) 90,000,000,003
(E) 91,114,114,114

Upon seeing this question, what is the first thing that comes to mind? Grabbing a calculator to add up the values in the expression? If you are able to quickly recognize that using the “5 x 2 pair rule” will allow you to efficiently attack the problem (see the solution below), the question becomes very basic, and you can avoid having to perform tedious calculations that are likely to result in a silly mistake.

Solution:

Notice that there is at least one (5 × 2) pair contained in the product of these numbers. It follows that the units digit must be a zero. The only number with zero as the units digit is 87,178,291,200.

Answer: A

This is just one example, but hopefully you can see that by a) recognizing what the question is asking and b) properly attacking the question, your propensity to make a silly mistake greatly decreases.

So, to improve your quant score, you need to go through GMAT quant carefully to find your exact weaknesses, fill gaps in your knowledge, and strengthen your skills. The overall process will be to learn all about how to answer question types with which you currently aren't very comfortable and do dozens of practice questions category by category, basically driving up your score point by point. For example, if you find that you are not strong in answering Number Properties questions, then carefully review the conceptual underpinnings of how to answer Number Properties questions and practice by answering 50 or more questions just from Number Properties: LCM, GCF, units digit patterns, divisibility, remainders, etc. When you are working on learning to answer questions of a particular type, start off taking your time, and then seek to speed up as you get more comfortable answering questions of that type. As you do such practice, do a thorough analysis of each question that you don't get right. If you got a remainder question wrong, ask yourself why. Did you make a careless mistake? Did you not properly apply the remainder formula? Was there a concept you did not understand in the question? By carefully analyzing your mistakes, you will be able to efficiently fix your weaknesses and in turn improve your GMAT quant skills. Number Properties is just one example; follow this process for all quant topics.

Each time you strengthen your understanding of a topic and your skill in answering questions of a particular type, you increase your odds of hitting your score goal. You know that there are types of questions that you are happy to see and types that you would rather not see, and types of questions that you take a long time to answer correctly. Learn to more effectively answer the types of questions that you would rather not see, and make them into your favorite types. Learn to correctly answer in two minutes or less questions that you currently take five minutes to answer. By finding, say, a dozen weaker quant areas and turning them into strong areas, you will make great progress toward hitting your quant score goal. If a dozen areas turn out not to be enough, strengthen some more areas.

So, work on accuracy and generally finding correct answers, work on specific weaker areas one by one to make them strong areas, and when you take a practice GMAT or the real thing, take all the time per question available to do your absolute best to get right answers consistently. The GMAT is essentially a game of seeing how many right answers you can get in the time allotted. Approach the test with that conception in mind, and focus intently on the question in front of you with one goal in mind: getting a CORRECT answer.

In order to follow the path described above, you may need some new quant materials, so take a look at the GMAT Club reviews for the best quant courses.
