Hi 23anshul,
I'm sorry to hear that your 3 attempts did not turn out better. Since you've been studying for so long, it's possible that you developed some 'bad habits' during your earlier studies that are currently keeping you from scoring higher. Before we discuss any of those potential issues though, it would help if you could provide a bit more information on how you've been studying and your goals:
1) On what dates did you take each of your 3 Official GMATs and what were the Quant and Verbal Scaled Scores for each?
2) How long did you study before each attempt? For this 3rd attempt, how many hours did you typically study each week?
3) What "brands" of CATs/mocks have you used over the course of ALL of your studies?
4) On what 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)?
5) When are you planning to apply to Business School and what Schools are you planning to apply to?
If you took your GMAT at a Test Center, then you might also choose to purchase the Enhanced Score Report. While the ESR doesn’t provide a lot of information, there are usually a few data points that we can use to define what went wrong on Test Day (and what you should work on to score higher). If you purchase the ESR, then I'll be happy to analyze it for you.
GMAT assassins aren't born, they're made,
