Hi kgmat12,
I'm sorry to hear that Test Day didn't go as well as planned. While not answering those last 2 questions would have likely cost you some points, there are likely additional issues that hurt your Score (such as having to rush through a bunch of questions at the end of the section - and likely getting those questions wrong). Assuming that you're interested in retaking the GMAT, before I can offer you any advice for this next phase of 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 did you score on the Official GMAT (including your Quant and Verbal Scaled Scores)?
2) How long have you studied? How many hours do you typically study each week?
3) What study materials have you used so far?
4) 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)?
Goals:
5) Is your overall goal score 650 or something else?
6) When are you planning to apply to Business School?
7) What Schools are you planning to apply to?
You might also choose to purchase the Enhanced Score Report. 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,
