Hi mangoleaf,
Back in late May of this year, you were considering enrolling in a GMAT Course. Did you end up taking a Course of did you continue to self-study? 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) How long have you studied?
2) What materials have you used?
3) Did you take the FULL CAT each time (with the Essay and IR sections)?
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?
Thankfully, the GMAT is a consistent, predictable Exam, so you can train to score at a higher level.
GMAT assassins aren't born, they're made,
