Hi pj2294,
What you're asking about - and what you ultimately need to work on - might not be the same thing.
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). Since you purchased the ESR for your Official GMAT, then I'll be happy to analyze it for you. If you would rather not publicly post it, then you can feel free to PM or email it directly to me.
Beyond that data, before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How many times have you taken the Official GMAT and how did you score on each attempt (including the Quant and Verbal Scaled Scores)?
2) How long have you studied in total? Over the last 3 months, how many hours did you typically study each week?
3) What study materials have you used over the course of ALL of your studies? What “brands” of CATs/mocks have you used?
4) On what dates (or approximate 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)?
Goals:
5) What is your overall goal score?
6) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
