Query: The cover lies!

The cover of this book promises four free online practice tests, but then they only let you do one. You have to pay for any more than that. Also, the vocab list is short and too easy, and there aren't nearly enough practice questions (especially considering that you only get one practice test!). This book has a few good tips, but you can get those from another study guide that also provides practice tests.In short, this book will NOT prepare you for the GRE. Spend your money elsewhere!
