Hi swean,
You have plenty of time before the Round 2 application deadlines - which is good. In that way, you do not have to 'rush' through this next phase of your studies, but you do have to be efficient (since beyond studying, you'll also have to work on your application).
To get a better sense of which areas you should specifically work on, we'll need to better define WHY you're getting questions wrong. As such, I'd like to know a bit more about your last CAT. While a full Mistake Tracker would provide a lot more information, there are some basic questions that you should be able to answer (and the more EXACT you can be with your answers, the better):
After reviewing each section of this recent CAT (the 660/Q46/V34), how many questions did you get wrong....
1) Because of a silly/little mistake?
2) Because there was some math/verbal that you just could not remember how to do?
3) Because the question was too hard?
4) Because you were low on time and had to guess?
5) How many Verbal questions did you 'narrow down to 2 choices' but still get wrong?
GMAT assassins aren't born, they're made,
