Hi manish1005,
I took the GMAT twice this year and I really know what you are feeling. The first step is relax. In my opinion, you could take another Test of the
GMATPrep Software tomorrow and no more. I think that is better for your mind to have some rest and relaxation.
If your GMAT will be in 4 days, tomorrow and the day after tomorrow read all the topics for
AWA (Friends.. Just 4 more days for my GMAT... Please help!!), Issues and Arguments. This will help you to be familiar with the topics and skip any "strange" word in case you are non native speaker
Then, put your books into a drawer, shut down the computer and go out with your familiy or your friends. Believe me. If you relax your mind, you would be able to concentrate in a better way on the Real Exam.
I hope this helps you. Let us know about your GMAT experience and your great Score.
Good Luck
