Hi Shouvik,
I'm sorry to hear that Test Day did not go as well as hoped. 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 did you typically study each week?
2) How have you scored on EACH of your CATs/mocks (including the Quant and Verbal Scaled Scores for EACH)?
3) How have you scored on EACH of your Official GMATs (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your goal score?
5) When are you planning to apply to Business School?
6) What Schools are you planning to apply to?
While the Enhanced Score Report 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). Since you've purchased the ESR, then I'll be happy to analyze it for you. To include attachments in your posts/PMs, you need to have at least 5 posts in the forums. If you'd rather not go through those extra steps, then you can feel free to email me your ESR directly.
GMAT assassins aren't born, they're made,
