Hi ww1207,
GMAC has publicly stated that the Official Score that you earn on Test Day is within +/- 30 points of actual ability. As such, your 2 Official Scores show that you essentially performed the same each time (about 610 +/- a few points). You handle certain aspects of the GMAT consistently well, but you also make certain consistent mistakes.
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) On what dates did you take each of your practice CATs? Which 'brands' of CATs did you use?
2) How have you scored on EACH of your CATs (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
3) What is your goal score?
4) When are you planning to retake the GMAT?
5) When are you planning to apply to Business School?
6) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
