Hi bhatla17,
While working through sets of practice questions and quizzes can help you to hone individual skills, the only practical way to assess how you might score on the Official GMAT is to take a FULL-LENGTH practice CAT under realistic testing conditions that match up with what you will face when you take the Official GMAT.
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:
1) How long have you studied in total? 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)?
4) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
