The 'Revised GRE' is a big improvement on its predecessor. When beginning your GRE preparation you must know what the test designer says about its own test. This book is published by GRE and contains lots of practice questions. Although it may not be the only book or course you use to prepare for the GRE, it is the one book that you must include in your GRE preparation.
It deserves 5 stars because it is published by GRE.
The seller sent my book quickly and it arrived as advertised, in perfectly new condition. I also saved a bunch of money buying here instead of the GRE website, although shipping costs were a bit of a bummer.
