Well my preparation spanned over months. As an engineer who works off shore for 12 hours a day finding time to learn was difficult. I was however able to squeeze in three or two works to do some learning. For the Quants, Nova and Barron’s is more than enough. Also make sure to make use of this forum. There are a lot of questions which can help. U might want to peep at Dr. Raju forum once now or then. Do not depend too much on it as you can easily make 800 in the Quants. For me, I messed up a lit and was too relax during the test. For the verbal, the Barron’s wordlist is must. You will need to familiarize your with the words and their definition. Also make the Big Book a companion. It is very useful and will serve you well. Also make sure to go through all words on Dr Raju database. I had about 80% of the words from the past database.
