I bought MGMAT's individual study package. A tutor said she likes to have her students go through Manhattan's GRE six books on math first, and then move to the GMAT prep after. She only does this for candidates who are not strong in math. I fall into that category, but it's just because I haven't taken a math since undergrad.
What are people's thoughts on this approach? I'm thinking about buying the six book package off of Manhattan's GRE store for $100.
Also, any other books I should know about to crack 700?
