Hi Tim1996,
Period review of concepts (and some practice questions) is often a good use of study time - and some GMATers find that reviewing a Mistake Tracker/
Error Log can also be beneficial. This can help to keep content knowledge (re: formulas, grammar rules, etc.), Tactics and GMAT patterns fresh in your mind.
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:
Studies:
1) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far?
3) On what 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)?
Goals:
4) What is your overall goal score?
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,
