Hi aa008,
I'm sorry to hear that Test Day did no go as well as hoped. GMAC has publicly stated that the Official Score that you earn on Test Day is within +/- 30 points of actual ability. Assuming a similar 'swing' in how your CATs function, your 2 CAT scores - along with your Official GMAT Score - show that you essentially performed the same each time (about 600 +/- a few points). You handle certain aspects of the GMAT consistently well, but you also make certain consistent mistakes (the differences in your Score could come down to just a few 'lucky' guesses on a few questions).
You might 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 (and what you should work on to score higher). If you purchase the ESR, then I'll be happy to analyze it for you.
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:
Studies:
1) How long have you studied?
2) What study materials have you used so far?
3) Are these the only 2 CATs that you have taken? If there were others, then how did you score EACH of those CATs (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) When are you planning to apply to Business School?
5) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
