Master the GRE, 2007/e w/CD-ROM
Arco
This book is a waste of money and may actually cripple your GRE test-taking ability. I took one of its computer-based practice tests and found the math questions to be extremely poorly worded and unlike anything that appeared on the actual GRE. Also, the scores were completely inaccurate, low-balling my actual score by hundreds of points on each section (!). Stick to Kaplan and Barrons, both of which are excellent guides. And if you want more practice, go to the ETS website and download their two practice tests for free.
