Query: Great Review of GRE Math Concepts

This book provides an excellent review of most of the math concepts covered on the GRE. Each chapter begins by clearly explaining a concept, and continues by offering TONS of practice exercises and tests. Using this guide and the questions from "GRE: Practicing to take the General Test" by ETS, I was able to score 780 on the GRE Math.One warning about this book: It does not address some of the more advanced concepts that may appear on the GRE CAT when you are scoring in the 700-800 range. For example, I encountered several questions about probability and statistics, two topics that I did not find in this guide.The great thing about this book in comparison to the Kaplan GRE Exam 2003 is that it's not just about Kaplan test-taking strategies. Instead, the author goes to great lengths to make sure you are prepared to handle the vast majority of the actual math concepts found on the GRE.
