Hi jppresa,
A 720 is a fantastic overall Score for a practice CAT/mock - and assuming that you took this CAT in a realistic fashion that matches-up with how you will take the Official GMAT, then you likely have really strong overall critical-thinking skills. Depending on the other details of your studies so far, you might reasonably plan to take the Official GMAT sometime soon.
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? How many hours do you typically study each week?
2) What study materials have you used so far? What “brands” of CATs/mocks have you used?
3) On what dates (or approximate 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) Are you planning to take the At-home GMAT or are you planning to take your GMAT at a Test Facility?
GMAT assassins aren't born, they're made,
