Hi GoodGuy,
From your post, it sounds as if you plan to take the GMAT sometime soon. If that's the case, then you might end up needing more time than you have allotted before you can properly learn and master the concepts that you're interested in. Before I can offer you any specific advice for 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 long have you studied?
2) What study materials have you used so far?
3) How have you scored on EACH of your CATs/mocks (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your goal score?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School?
7) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
