Hi AurelianInvictus,
A 660 is a strong initial CAT score (the Average Score on the Official GMAT hovers around 550 most years). That having been said, if that's the only CAT/mock Score that you have, then it's tough to say for sure what your actual 'ability level' is right now (re: you might have gotten a bit lucky or unlucky when taking this CAT, meaning that you might be more likely to score lower or higher if you took the Official GMAT tomorrow).
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 “brand” of CATs was this?
3) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
