Bests & Worsts Reviews from Amazon

Do not buy this book if you are trying to effectively review for the quantitative reasoning section of the test. I used this book to study for several months for the GRE, and I took three of the four practice tests and earned above average scores. I felt fairly confident about at least earning an average score on the math section. I thought that buying a book that is manufactured by the company who makes the test would ensure that I earn a good score (with focused studying of course). NOPE. Test day comes, the quantitative reasoning section is at the least 20x harder than any of the practice tests and review questions. My unofficial score is several points below average, despite studying furiously for several months and always earning above average scores. I felt so confused about what happened because I had worked so hard--this wasn't a case of pathetically studying. Later I talked to some other students in my research lab, come to find out ETS's practice materials are not good tools. Kaplan and Manhattan are apparently better, so I will be buying their practice guides to study for when I retake this exam. I don't write product reviews, but I hate the fact that I just wasted about $235 on this book and my original GRE and will have to shell out another $205 for my retake. I don't know if this is some scam so that ETS makes more money from people who have to retake the test after using their bogus practice guides, but I do know that just because it says they make the test does not mean that it is a good product. I wish I knew that ETS's books are bad. Do not waste your money on this book, because you will have to waste more money to retake the GRE.
