Hi seminajk,
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). I'll be happy to analyze your ESR, but I'll need to see the FULL ESR though. If you would rather not post it publicly, then you can feel free to PM it directly to me.
Beyond the data in your ESR, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) What type of study routine have you followed? How many hours do you typically study each week?
2) Have you used any other study materials besides the OG?
3) How have you scored on EACH of your CATs (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your goal score?
5) When are you planning to retake the GMAT?
6) When are you planning to apply to Business School?
7) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
