GMAT Math

Hi,

I am scheduled to take the GMAT in three weeks and I need to dramatically improve my Quant score. Below are my GMATPrep practice test scores:

640: 35V (74%) 42Q (57%)
630: 35V (74%) 41Q (54%)
660: 39V (88%) 42Q (57%)

Topics I struggle with:
1. Abstract Algebra (applied, first & second degree problems)
2. Combined Work/Average Problems

OG categorizes my most missed question types as, Algebra: Applied Problems (38,79,86,98,113,119,123,129,153,162,168,203,205,214,224) & Arithmetic: Operations on Rational Numbers (40,76,85,97,100,108,133,149,150,151,158,170,171,199,200,218,222,227)

Although my quant score hasn't improved, when I reviewed my most recent practice test, 6 out of the 10 questions I missed were careless mistakes. When I was able to review the questions without a time constraint, they were fairly easy to solve.

I have completed every question in the OG13th, and kept an error log. Of the questions I either missed or spent too much time on, I have created problem sets and reworked them.

I don't know how to best utilize my time studying quant moving forward. Should I keep reviewing old problems and learning the patterns, or should I do a lot of new practice problems? I'm frustrated because they way I have been studying obviously hasn't been working. I have been studying for a little over a month. I have less than three weeks and I would ideally like to be scoring in the 80% range for Quant.

Any study advice would be greatly appreciated given my timetable for the exam.

Thank you!

Hi WPRO,

Scores DON'T improve due to various reasons:

1) Lot of silly mistakes
2) Poor understanding of Necessary Concepts (Number Properties, Geometry, Inequations primarily)
3) Poor ways to attack DS Questions
4) Poor speed of solving the questions and rushing towards the end of test
5) Your own reasons (Concentration etc.)

What is the primary reason with you for such a NOT-SO-GOOD performance?

Where the practice makes a substantial growth in the scores, Just finishing every material is not the key to get a good score. You must solve the questions in such a manner that your take-away from the questions is maximum and your ability to apply the concepts in various other problems also improves.

I would suggest that you should be taking some guidance as to what is the major problem with your problem before you lose a lot of time which you can use for further improvement.

I would say that it's a poor understanding of how to apply the necessary concepts. I don't have a problem understudying the theory behind the question. Intuitively it's not difficult for me. I believe the difficulty stems from my inability to apply the theories/laws to actual problems. For abstract algebra problems it is my inability to set up the equation with variables instead of numbers. Once the problem is correctly set up, I have no issues solving. The problem is getting to the point where I can plug and chug.

For me, DS questions are easier than PS questions.

My problem is recognizing how to set up the problem, and the most efficient method to apply. I haven't grasped how to study the answers in such a way that I understand every element of the question.

I don't think the math is difficult itself, I just haven't cracked the code of how the GMAT manipulates basic concepts to make them appear difficult. I haven't recognized the important patterns.

Thank you, Brent and Bhoopendra.

You got the nerve of GMAT by saying "I don't think the math is difficult itself"

Also you surprised me by mentioning that you find DS easier than PS which is not the usual case with majority of test takers.

Application of concepts is a problem when you stick to one way of solving the question. You must always look for alternative approaches so that you brain can be tuned to think on other dimensions as well.

Solve the Questions of Word Problems and Master the questions of Time and Work and Speed, time Distance topics which offer you to make equations in various ways.

On Beat the GMAT almost every questions has various ways to solve it. So identify the topic that bothers you the most and start looking at the methods of solving those questions. I am sure they will be of great help for you.

All the best!!!

Your Quant performance on these CATs is consistent, which means that you "see" the GMAT in a certain way and haven't been able to adapt. You mention wanting to score 80%, so I think you mean the 80th percentile, which is a Q49.

To raise a Quant Scaled Score in the low-40s to 49 takes time. While you could certainly improve in 3 weeks, you'd have a better chance of making a BIG improvement if you had more time than that. Do you have the flexibility to push your Test Date back? I know that most people don't "want" to change a Test Date once they have one, but your goal might necessitate it.

How long have you been studying? What resources (Courses, Books, etc.) have you been using?

Hi Rich,

Thank you for your response. I have flexibility, but given the upcoming round 1 deadlines, I would prefer to take the GMAT before September. Obviously if I'm not close to my goal by the week before the test, I will push it back because a poor GMAT score with the round 1 application is a lot worse than a solid GMAT with a round 2 application. However, there are other factors involved with my decision to take this test in the next few weeks. I will be moving out of the country in September and it's important to me to have the GMAT/application process behind me.

I have been studying for about 4 weeks. I've completed the OG 13th edition, and currently have access to Kaplan's on-demand class until September 2nd. I am primarily using the Kaplan resource for the quiz bank (I have done 600 math practice problems).

I don't know if it's better to focus on one specific topic (Algebra), try to improve Quant as a whole, or to keep studying Quant & Verbal equally. I would like to score a 49 (80th percentile), but I'm worried if I neglect studying for the verbal section, my Verbal score could fall. It also seems that an improvement in math will significantly improve my overall score.

I've read plenty of posts and advice from other people, I just don't know how to use my study time effectively and efficiently. What I have been doing obviously isn't working.

Thank you again!

Also, I realize that the Kaplan CATs are not the same as a GMAT Prep practice test, but below are my two Kaplan CATs:

640 - 44 Q (66th percentile), 38 V (83rd percentile)
650 - 48 Q (80th percentile), 35 V (74th percentile)
