Hi ridzseeker,
Many Test Takers spend 3 months (or more) of consistent study time before they hit their 'peak' scores. From what you describe, it sounds like your studies have been inconsistent. To improve to any reasonable degree, you have to accept that the overall training process will take time - and then you have to commit the necessary time and effort.
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) What study materials have you used so far?
2) How have you scored on EACH of your CATs (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
3) What is your goal score?
4) When are you planning to apply to Business School?
5) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
