Hi Mansi89
If it's really been over 7 months since you've taken a practice CAT/mock, then you really should take one soon (perhaps this weekend); make sure to take it in a realistic fashion (take the FULL CAT - with the Essay and IR sections, take it away from your home, at the same time of day as when you'll take the Official GMAT, etc.). Once you have that score, you should report back here and we can discuss how best to proceed.
Beyond that data, 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? Have you taken any "time off" during your studies?
2) What study materials have you used so far?
Goals:
3) What is your goal score? Is it 650 or something else?
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,
