Hi nikhilchugh95,
I'm sorry to hear that Test Day did not go as well as hoped. In a prior post, you stated that you planned to take the GMAT back in October, 2018. In your post here, you've stated that you took the GMAT in April. Did you end up taking the GMAT more than once (and if so, then how did you score on EACH of your Official GMATs?)?
When these types of score drops occur, the two likely "causes" involve either something that was unrealistic during practice or something that was surprising (or not accounted for) on Test Day. 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 long did you study before each of your Official GMATs?
2) What study materials have you used so far?
3) On what dates did you take EACH of your CATs/mocks and how have you scored 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 take the GMAT?
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,
