This will be my third and final attempt for the GMAT. I do not want to take any chances and want to be fully geared up so that I can get into one of the best B-schools. I am targeting a score of 750+. Can I achieve this?

Hello Kanea,

I have to be honest with you. I don't know. A 750+ score is extremely difficult to get. Without knowing anything about your background, your standardized test taking methods, and your study techniques, its really impossible for me to make any reasonable assessments. Where are you from ?

cheers,
Steve

That's a good ! I am trying to carry the same mentality as one needs the boost up theory in these kind of competitive exams.

To clear the Gmat we have to improve our maths skills. Maths is a typical but necessary part of Gmat.

several people has asked me if it is possible to improve your quant score form 44-46 range to 50+, how this can be done and how much time is needed..... so i gave it some thought....

obviously - everyone is different.... each has different weaknesses and stregths so there is no generic answer to all - but still, i think that there can be some rough guidelines for doing this leap.... here are my thoughts about it.

if you are constantly performing at the 44-46 quant range (previous gmats, trustable prep material) i guess you:
- mastered most of the required skilled
- understand the structure and requirements of gmat math questions

your problems are likely to be in the following areas:
- "silly mistakes" i.e. things that in the pressure of the gmat you do wrong although you know and understand them
- get yourself into unnecessary complications in solving some of the questions.
- timing issues... there are some things that just take you too much time to get right.
- mistakes that are a result of a subtlety of concepts that you werent sure about (which made you both spend time, eventually guessing or answering without confidence, sometime getting it wrong)

the most common prep mistake (in my view...) that people do:
- concentrating on advanced concepts and hard questions. the ROI of this kind of prep is small (it would be higher if you were to advance for 48-49 to 51).

The GMAT Quantitative Ability section includes Data Sufficiency and Problem Solving Questions. Problem solving questions come in 3 different varieties: Arithmetic, Geometry, and Algebra.
Algebra

This section usually accounts for 20% to 25% of the quant section. The most important key algebra topic that has been asked repeatedly in GMAT tests are solving various equations and word problems. The algebra section is very critical for getting high GMAT score.
Topics and Examples

Understanding and being able to set up and solve equations is a large part of every mathematics course and therefore you can bet it’ll take up a significant portion of the GMAT quant section. The idea is quite simple- you need to be able to convert a word problem into an equation, and solve it. Here is a sample question:

I have a piece of wire that is 50 feet long. I cut it into two pieces, and one of the pieces is 13 feet longer than the other. What is the length of the shorter piece?

Let’s set up an equation first. Say S is the length of the shorter piece. Then, since the longer piece is 13 feet longer, it’ll be S + 13. Now, the total length is 50, so S + S + 13 = 50, so S = 18.5 feet.

This is a very straightforward example. You will also need to be able to handle polynomials, solve two simultaneous equations in two variables, second-degree equations, and inequalities. Here is a slightly more complicatde example:

If \frac{6 - x}{3 + 2x} = x, find x ^ 2 + 2x.

This is pretty easy. Just multiply both sides by 3 + 2x to get 6 - x = 3x + 2x ^ 2, so 2x ^ 2 + 4x = 6. Dividing everything by 2, you find that x ^ 2 + 2x = 3.

You will have to be able to solve these and other similar types of questions if you want to ace the GMAT.

The Quantitative Section may be the easiest section to improve in – if you prepare correctly, giving you the golden opportunity to significantly improve your overall score. The following tips can help you understand how to boost your score.

Focus on just the Quant. Section: Verbal, Analytical Writing don’t even exist right now. First, you need to become proficient in one section. Then move onto another, then the last. Then review them all collectively. Studies indicate that the brain works best when it can see how all the information connects and relates. But, with the GMAT, it’s simply too big of a monster to tackle at once. So, try to get a solid understanding of each section; then connect them all.

Step one Read up: Before you dive into practice tests, read, read, read and read some more. Some books specialize in GMAT Quantitative, and others simply have it as a section. Both will work out well. In this section, you will need to know arithmetic, elementary algebra and basic geometry. You will see two types of questions: problem solving and data sufficiency.

Data sufficiency tips: These problems pose a question and then provide two potential answers. You must decide if one, both or neither of the statements are sufficient enough for the question.

First off, memorize all five possible answers (they are listed below) to save tons of time. Then, look at each numbered statement individually and use process of elimination. It may seem odd, but don’t trust your eye or your first instinct – because that is exactly how test makers create traps. Instead, work through the problem. But most importantly, rely on common structures and themes – instead of numbers to solve each answer. You can master that last technique by writing your own questions and changing the numbers in the problems. That forces your brain learn structures, instead of numbers, which can dramatically improve your accuracy and speed.

Problem Solving: For these questions, you will need your basic mathematic skills (geometry and algebra and not calculus or trigonometry). Here, you will see multiple choice calculations and word problems, most of which will be pretty similar to what you saw in previous math classes/standardized tests.

Make scrap paper your new best friend and use as much of it as possible. Writing out all the steps to the problems can help you avoid careless mistakes. Read the problems very carefully because test makers load questions with traps. Making educated guesses can be very effective for this section, as it will save you buckets (and we mean buckets) of time without sacrificing a lot of accuracy.

Practice test: Okay, now you’re ready for your first practice test. Don’t be over-concerned with your score. Just take one to get through it. Highlight any questions you were confused on or any that took you an incredibly long time. Then, review those questions at length with your tutor to learn how to use themes and structures to answer them correctly and quickly.

Practice questions: Not tests, but just questions. Have your tutor create a list of questions that are problematic and time consuming for you. Run through them over and over and over again. In time, you will be amazed at how much easier these questions will become.

Real practice test: Your brain likes consistency; so try to mimic the test scenario by taking an entire, timed test in a public place on a computer, like a library or coffee shop to help you get used to thinking with other people around. After you do this, start all over again until you’re satisfied with your score.

Understand time: You have to answer 37 questions in 75 minutes, which gives you about 2 minutes per question. So, if you find yourself taking more time, then you need to speed it up and maybe even start guessing.

Always finish the test: There is a penalty that some estimate to be as high as 30-50 points for not finishing the test. But, if you blindly guess on the last 10 questions, the test will know and penalize you for it. So, pace is incredibly, incredibly important. But, if you must – blindly guess on the last questions.

Thank you, richardshelton, for sharing your ideas with us.

I'd like to rewrite the question statement of your example #2, so that other users may understand it easily. Here it is:

Quote:
If (6 – x) / (3 + 2x) = x, find x² + 2x.
