Hi Maddala,
You're focused on the Quant section right now, so I can offer some suggestions. However, you have not defined your OVERALL goals - and it might be that your time would be better spent working on the Verbal section during these last few weeks of study.
I have a few questions about how you perform on the Quant section of your CATs:
1) After reviewing the questions that you've gotten wrong, can you define WHY you got them wrong?
2) How often was it because of a silly/little mistake?
3) How often was it because the question was just too hard?
4) Do you have trouble finishing the Quant section on time (and do you have to guess on questions just to finish?)?
What is your overall score goal?
How have you been scoring on your CATs (including the Essay and IR sections)?
GMAT assassins aren't born, they're made,
