Hi Sajjadmahessar,
Based on your initial post, I'm going to assume that you do not yet feel ready to face the overall GMAT (meaning that you are not close to your Goal Score yet). You don't actually have to take the Exam tomorrow, if you don't want to - although you won't receive any type of refund for not showing up. If you choose not to take your GMAT as scheduled, then it will NOT count towards your 8-attempt limit and no record of that attempt will appear in your profile. Assuming that you will (re)take the GMAT at some point later on this year, you might still want to stick with this appointment - and consider this attempt as something of a 'test run', in which you can learn all of the various aspects of Test Day (the travel time, layout of the location, check-in procedures, etc.) so that you can be even more prepared for that later attempt.
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far? 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,
