Hi koolarijeet,
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 did you study before taking the Official GMAT (in September)? Have you been studying consistently since then (or have you taken 'time off' in between?)?
2) What study materials have you used?
3) On your CATs, have you taken the FULL CAT each time (with the Essay and IR sections)?
Goals:
4) When are you planning to retake the GMAT?
5) When are you planning to apply to Business School?
6) What Schools are you planning to apply to?
