Hi Rohit,
Are you taking your GMAT on April 23rd so that you can take it again (if necessary) and still make the May 30th deadline?
When you took this recent CAT....
1) What were the Quant and Verbal Scaled Scores?
2) Did you take the ENTIRE CAT (including the Essay and IR sections)?
3) Did you finish any of the sections early? Did you have to rush to finish any of the sections (and just guess on a bunch of questions)?
If you took the FULL CAT and did so under 'test-like' circumstances, then you're remarkably close to your goal, so you might be studying in the proper way right now. A full review of this CAT is probably warranted. It's not enough to identify your 'weak' areas, you have to define WHY you're getting questions wrong. When you can answer THAT question, then you'll have to something that you can focus on (and fix).
GMAT assassins aren't born, they're made,
