Heya,
[GRE]
In my experience, I did find number2.com a lil difficult to get the perfect score. But barrons review books were pretty fine. But must say, the powerprep questions were rather easier than the actual GRE quants. Moreover during the GRE, I found my self running out of time towards the end and had to step up my pace to complete it just on time. Well, the scores I received in the powerpreps were actually exactly what I got for my GRE. So for quants, u may get questions that need a little more working than the pp questions but most importantly, time management is essential.!
Regards.
