This book is a complete waste of time. The math problems are in no way similar to the ones on the GRE, and it is so filled with errors that the authors and the editors ought to walk the plank and dive deep into unemployment. Everyone buying this book should demand a refund.
At first I really enjoyed this book. It make some good points and had sort-of an insider's perspective. After the first chapter, however, there's not a single new point. Smith apparently wanted to write a book, but had hardly anything to say that could not be stated on the back of an envelope. If this book were three-four pages it would be a good read, now it is just dull-city.
