Hi jpvemula,
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:
1) Have you taken any of the GMAC CATs?
2) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores)?
3) Did you take the ENTIRE CAT each time (including the Essay and IR sections)?
4) What is your overall score goal?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School?
GMAT assassins aren't born, they're made,
