Basically GMAT Quantitative Section is meant to check your content and analytical knowledge of basic math concepts, including arithmetic, algebra, and geometry.
The section consists of two question types:

Data Sufficiency and Problem Solving.

Data Sufficiency questions contains an issue and a couple of statements of knowledge. It’s your job to work out whether the statements provide sufficient data to answer the question. This question type really requires you to quickly identify what information you'd got to know and to efficiently eliminate incorrect answer choices.


You’ve been here before…Problem Solving is that the classic standardized test question type. You’ll be presented with an issue and 5 possible answer choices. Problem-solving questions test your skill in high school-level math. Simple, right? Well, when was the last time you tried your hand at high school math questions? If your answer is high school then you'll be wanting to brush up. The key to success is to obviously understand what the question is asking and to avoid the trap answer choice.
To master both these sections, here are some specific suggestions that you simply can start using to enhance GMAT Quant scores.

1. Get your Basics Sorted: The GMAT tests you on high school math. Way too many of us fuss about learning advanced concepts without investing sufficient time into getting the essential concepts right.

Mastering math, especially the math tested on GMAT quant, requires that you simply take a linear, systematic approach towards developing your knowledge and skills if you skip to the hard stuff, it'll be challenging for you to develop a robust command on the fabric.

2. Learn to Use Numbers Effectively: Remember, the GMAT doesn't worry about how you get to the solution, but you've got to get it. A good scorer is best at “hacking’’ his way through the test.

3. Don't Jump to conclusions: This has always been, and can always be, an issue that students at some stages of their quant preparation find the conclusion that what percentage of questions they aim to attain. Go thoroughly through all the concepts of each and every quant topic.

4. Identify simpler solutions: Every GMAT quant question features a certain finesse there to, a finesse that's engineered by the test maker.

5. Use logic over Math (Especially on Hard Questions): One among the themes we always stress is that the GMAT Quant section isn't, primarily, a math test, find logic to unravel it.

6. Don't depend only on the Official Guide: Don’t rely only on the Official Guide, it still gets people just within the middle of the bell curve, i.e., those that get around 40-44 as a GMAT quant raw score.

7. Never be rigid with techniques: Never be rigid on one method to unravel problems, develop new techniques to unravel it easily and accurately.

8. Master data sufficiency: Simply, the DS section of the quant is different.
It’s different because its need some criteria to unravel:
• Write down all the important information within the question stem.
• Always break down and rephrase any equation, inequalities, fractions, etc.
• Always translate word problems on DS into an algebraic equation.
• Never make assumptions.
• Never dispense a statement as insufficient simply because you are feeling the statement is insufficient.
• In questions, where you're forced to figure with numbers, always test numbers systematically.
