Has anyone used the Princeton Review 2012 to study for the GRE? I have a question about interpreting scores. The books tells you to add up your correct answers for the two sections, so you can have a maximum of 40 points. Yet in the score interpretation for verbals 51-56 is considered above average and 48-52 for Quantitative. I know that books tests aren't that good to help, but I still want some feedback.
