Hi beebuzz0504,
I'd like to know a bit more about your CAT Scores:
1) When did you take each CAT?
2) What were the Quant and Verbal Scaled Scores on each of these CATs?
3) Did you take the ENTIRE CAT each time (including the Essay and IR sections)?
4) Did you take them at home?
5) Did you take them at the same time of day as when you plan to take your Official GMAT?
6) Did you ever do ANYTHING during your CATs that you couldn't do on Test Day (pause the CAT, skip sections, take longer breaks, etc.)?
7) Did you ever take a CAT more than once? Had you seen any of the questions BEFORE?
Assuming that your general 'ability level' is in the high-500s, you will likely need at least another 3 months of consistent, guided study to get to a 720+. This is meant to say that you might need to change your timeline a bit to allow for the necessary study time.
GMAT assassins aren't born, they're made,
