Hi smartguy595,
Before I can offer any advice, I'd like to know a bit more about how you studied:
1) What resources did you use during your studies?
2) How did you score on each of your practice CATs (including the Quant and Verbal Scaled Scores)?
3) When are you planning to apply to Business School?
4) Do you know which Schools you plan to apply to?
Since you've studied for over 3 months already, you likely know a lot about the overall content of the Test. Given your Scaled Scores on the Official GMAT, I think that you will need to focus heavily on Quant and Verbal TACTICS as you continue to study. This will likely require at least another 2 months of work.
GMAT assassins aren't born, they're made,
