Hi pdas146,
When taken in a realistic fashion, a CAT is really a 'measuring device' - it will give you a realistic score and help define your strengths and weaknesses, but it will NOT help you to fix any of those weaknesses. Thus, reviewing each CAT (with the goal of defining WHY you got each question wrong) is an essential part of the overall GMAT training process. After reviewing this recent 590 CAT performance, how many questions did you get wrong because of a silly/little mistake (and by extension, what additional work could you have done - on your notepad - to make sure that that mistake does not happen again)?
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:
1) How many hours do you typically study each week?
2) What study materials have you used so far?
3) 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)?
4) 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,
