Smart, Pankaj...!
Then, I should tell you, Sree, that the best way to prepare for the test is to try and improve your vocabulary.
If you consider the large pool from which the questions for your test are picked from, you will quickly realize that knowing a handful of actual GRE (err... excuse me pankaj, high frequency).....questions is of no use. You can spend this time on better/more useful things!
All the best!
