Most Imp Tip : Bases on our students experience, some questions are very easy so one should only spend only about half a minute and some 4-5 questions are tricky and one has to spend 3-4 minutes to crack those tough questions. Some students couldn't complete the quantitative sections and most of them felt that thay should have done the easier questions faster rather than revising those easy ones again and again

Read the question carefully Some times they just add negate the positive statement say for example they may ask which of them was not true?. By making this a habit one can save 2-3 silly errors.

Use paper and pencil for short calculations and for taking note of eliminated choices.

In GMAT answer choices are arranged in ascending or descending order so while guessing an answer or while working backwards one should always start from choice b or d as it will tell u in which direction u should move and may save a step or two ( same priciple is followed in Binary index seraching).

Do not waste time on lengthy calculations as GMAT questions are mostly based on tricks and they do not expect you to go on lengthy calculations. One may spend some time on trick else it is better to leave the question. Sometime it may be a test question for future GMATS ( Out of 37 question sin gmat only 28 are evaluated and rest are future test questions to understand their difficulty level based on your correct answers and time spent.

GMAT expects to u to do approximations as answers choices are rarely close. say 9.5 can be rounded of to 10 or 22/7 can be assumed to be 3.

In GMAT if u are weak on ceratin specific question types then do make notes and just practice those questions again and again so that one can save time on those questions. Some examples are given below

There is a big difference between a question asking "Which of the following may be true?" and one asking "Which of the following may not be true?" The test writers deliberately include answer choices that correlate to common misinterpretations of the questions.

Use your scrap paper for every question. No matter how easy a question appears, you should utilize your scrap paper. Seeing a calculation on paper will help you avoid.

Do not get bogged down with complicated or lengthy calculations. We have looked at hundreds of GMAT problem solving questions and found that they are.

The "guesstimating" technique is extremely effective on this exam. Most of the time, the answer to a problem-solving question is a value, and the values given in the answer choices will not be very close to each other. As a result, you can save time by 'guesstimating.' For example, if you know the value you're looking for is about 30%, and the answer choices are 4%, 13%, 29%, 47%, and 81%, you can safely guess that the correct answer is 29%. Congratulations - you just saved yourself a lot of time on this question, and avoided getting caught up in a longer calculation that might have resulted in a math error!

Convert quantities freely. There are often shortcuts available to you if you can recognize relationships between the numbers used in the problems. Keep in mind, the GMAT test writers never haphazardly select numbers for their questions. This technique is especially useful in narrowing down likely answer choices when you feel the urge to pull out a calculator. One easy conversion to remember is that, at least for purposes of the GMAT, p = 22/7.
