- i've done my maths from GRE (14th ed)
- (14th ed) GRE because that is the only edition that has questions based upon LOGICAL REASONING
- verbal from GRE as well as GAT (doggar publishers, muhammad idrees)
- for current affairs portion, i studied previous 6 monthly issues of Jahangir World Times, as they provide monthly mcq's, which helps a great deal
- 600 Common Errors book besides TOEFL for sentence correction

even so, as it turns out, i haven't qualified yet. so may be my strategy is flawed. do share your approach to it
