Hi nandinigarg0807,
I'm sorry to hear that your 2nd attempt did not turn out better. 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:
1) What type of study routine did you follow over the last 4 months? How many hours do you typically study each week?
2) What specific study materials have you used over the course of ALL of your studies?
3) 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)?
4) When are you planning to apply to Business School?
You might also choose to purchase the Enhanced Score Report for your recent attempt. 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,
