Query: don't think twice, buy the ... book for ur own good.

my recommendation for those who want to crack the test with great scores is studying the theory and practice questions from 'Barrons GRE book' first.Then go ahead and solve as many papers (more the better) as u can from the 'BIG BOOK'. The final step would be to take the practice test on the computer using the cd included in the Barron's book (if u already have an earlier edition, buy a separate cd for ...).though the paper pattern in the BIG BOOK is not similar to the CAT it gives a lot of practice in solving papers in limited time. the only disadvantage is that one doesnt get an explanation of answers. but once u go through the question again as u check the answers, u would definately realise ur mistake.the reason behind me awarding it 4 stars not 5, even after all the above goody goody matter is that the book does not follow the CAT pattern. believe me, if only they publish a latest edition accordingly, there would be nothing like it.
