suitable material for GRE?

Answer 1

Barrons guide is suuficient from my experience to learn as stage 1. Give urself atleast 6-7 months of every day reading. Maths is a piece of cake as it is school level.
For stage 2 you need to take practice tests. Kaplan used to have good material 3 years ago. They also come with study material.
For verbal use flashcards - very very useful. randomly pickin out cards and practicing over a period of time is very useful. Alternatively u can go thru a dictionary during free time.
Finally a grant / offer need not come only with GRE/TOEFL or anyother scores. If you have taken part in presentations and research on your own (especially since in India there is hardly any incentive provided for anything) you can provide that. Ofcourse they need to be good enough not namesake. Remember that a generic course attended to by many such as computer science may not be easy. But applying for a specific course matching your research interests can always yield better results.

Answer 2

I dont know if you are looking for a good study guide for it but I bought two that I found in the local bookstore and I made sure they had multiple practice tests. Then rather than actually "study" I took a practice test, reviewed my mistakes, took another, reveiwed, and kept on taking practice tests. In HS I nearly failed algebra 2 (and took NO MATH in my undergrad years) and when I took the GRE I Scored so well that Grad schools were offering me grants if I would attend. I definitely dont think this method is for everyone, but it worked for me. =)
