Hi callpranav,
Over the next couple weeks, it's important to determine where your weakest areas are and focus on improving on them. Have you kept an
error log over the course of your prep? If so, what are the areas you struggle with most? Try not to bog yourself down by trying to re-learn EVERYTHING you'll need to know for the GMAT - you probably understand more concepts than you currently realize. And as you get closer to the exam, take some time to relax. You've spent a lot of time preparing for the GMAT, and it's only healthy to give yourself a breather right before the GMAT.
Best of luck,
Rich
