I currently have the PR Cracking the GRE (2008 ed) book. I heard that the PR math isn't the best for preparing for the GRE. I've noticed that they do give really good "tricks," but I'm not sure if this is sufficient for preparing the GRE math section.
I'm decent at math and would most likely benefit from a "refresher" rather than something that explains algebra indepth again.
Given that, would you recommend the Barrons or Kaplan for math (or something else, ie Nova)?
I was looking around on amazon, and found that Kaplan has a couple of versions of its book preps. I don't have the money to spend $50+ on one prep book (considering I already have a book; I'm looking for something in the $25 or below range, ideally). Kaplan does have this "GRE Exam 2010: Strategies, Practice, and Review," has anyone had experience with that? Can it be used as a substitute for the $50+ premiere program? What about some of those "math workbooks" (I think Kaplan and Barron produce one), are they simply practice questions with no "review"?
