Hi Mandar24,
Since you've been studying for 3 months, it's important to define your current 'ability level' and goals - so that we make sure that this next phase of your studies is properly planned out. Working through lots and lots of practice questions might not actually help you to improve in the way that you think it might - and since the Official GMAT functions in a really specific way, you should want to make sure that you're properly training for THAT experience (and not simply working through sets of practice questions that approximately match the number of questions you'll see on the Official Exam).
Before I can offer you the specific advice that you’re looking for, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How many hours do you typically study each week?
2) What “brands” of CATs/mocks have you used?
3) On what dates (or approximate dates) did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your overall goal score?
5) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
