Hi ashszn,
Many Test Takers spend 3 months (or more) of consistent study time before they hit their 'peak' scores. In another post from about 1 week ago, you mentioned that you've been studying for just 1.5 months, so you might naturally improve as you continue to study. At this point, you have less than 4 weeks of study time remaining before your planned Official Test Date, so if you want to be efficient with the time that you have, then you might need to invest in some new study materials that will keep you focused on the proper Tactics to score higher.
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) Have you used any other study materials besides the books that you mentioned?
2) How have you scored on EACH of your CATs/mocks (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
3) What is your overall goal score?
4) When is your exact Test Date?
5) When are you planning to apply to Business School?
6) What Schools are you planning to apply to?
