Hi pratyushamrit03,

It appears that you're just beginning this process. If you can answer a few questions, then I will be happy to provide some advice:

1) When do you plan on applying to Business School? And what schools are you considering?
2) Since you're in school now, how much time will you be able to commit to studying for the GMAT?
3) Have you scheduled your actual GMAT yet? And if so, when is it?
4) Have you taken any practice CATs or acquired any practice materials?

To start off, you can download 2 practice CATs and some practice questions from www.mba.com. Take one of those practice CATs (it takes about 4 hours and you'll want to take the entire test to get a sense for how it "feels") and report back here with your score. Your study plan will depend somewhat on how you score.

GMAT assassins aren't born, they're made,
