Hi YNWA,
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 (and what you should work on to score higher). Since you're new to GMATClub, you won't be able to post it just yet, but if you email it to me, then I'll be happy to analyze it for you.
Beyond that data, it would help if you could provide a bit more information on how you've been studying and your goals:
1) Since you last took the GMAT, how have you scored on EACH of your CATs (including the Quant and Verbal Scaled Scores for EACH)?
2) Your next planned Test Date will be some time in the next 2-3 weeks. Do you have the flexibility to push back that Test Date if needed?
3) When are you planning to apply to Business School?
4) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
