Hello buddy as you want preparation tips on Graduate Management Admission Test(GMAT) so here I am getting the tips….

Consistency over intensity
One can compare GMAT prep with learning to play chess. It is not only necessary to learn and know all the concepts and tricks; it is also essential to be confident and quick in using them.

Create a learning diary
The numbers of concepts that are asked in GMAT questions are finite. Therefore a good method to improve and reduce your ‘white areas’ is to keep a learning diary. This means one should write down every unknown prep question and try to understand the correct answer and concept behind them.

Set an exponential GMAT prep timetable
It goes without saying that you need to leave enough time and plan effectively during GMAT preparation. Furthermore, I recommend that you take an exponential approach in prep time planning.

Train to use laminated drawing board during GMAT Prep
Many test centers offer only laminated drawing boards for calculations and sketches during the test. This can lead to irritation for those not accustomed to using an erasable overhead marker – especially left-handed people, who often tend to smear their notes. Knowing this, you should practice this during your preparation phase in order to avoid as many surprises on test day as possible.

Practice educated guessing
A good method in dealing with GMAT questions to which you are not absolutely certain of the answer is ‘educated guessing’. One can save time by quickly eliminating two or three wrong answers and then guess out of the rest.

Try to overshoot your target GMAT Score
Your preparation should target a GMAT score of at least 50 higher than you ‘need’. It is not uncommon for test takers to score 30 points more or less than they were expecting, depending on their individual physical and mental state on the test day and the questions they face.

Redo GMAT prep tests
One can get good GMAT prep tests from many sources and companies. The good thing about prep tests used by the better of these companies is that most of them use an adaptive question algorithm – as the real test does. So redoing a prep-test exposes you to a greater volume of questions.
