Straight Forward Guide
I had previously taken a GRE free test to confirm my suspicion that I needed significant study to prep for exam. After being out of university for over ten years my scores were sobering.My quantitative points improved a solid 100%! That in itself was worth every penny invested in these prep books. I scored average in the verbal section but I still experienced a 48% increase in points pushing me above the 90th percentile. Testking is a straightforward study guide with basically everything you need.

Right To The Point
Testking gets right to the point without a lot of useless information. Includes vocab words and definitions. This book has everything you need for a good price. I just took the free GRE test and got good scores- this book was a huge help. It breaks down how the test works and has good tips. I used it in conjunction with other books; It would have sufficed on its own. It clearly explained everything and gave me a better understanding how the GRE really works.Thanks to Testking again for being wonderful.

Strongly Recommended
I like the GRE test free review and tips in this book but the math problems are too simple and straightforward. If you are just going to use one GRE review book, I would strongly recommend buying Testking. I like how the math problems in Testking require a little bit more work. Testking provides a much more extensive list of vocabulary words.To be honest, I bought this book to make sure I would actually study for the GRE. This book really helped me prepare for the GRE.

Decent And Similar
The book is decent and similar to many other GRE test preps. The explanations are simplistic and very straight forward - anyone can understand the concepts outlined in the book. I will say this; the free GRE test is well written. The concepts are clear and easy to understand. I have been out of school for over a decade and can't remember the last time I have taken a timed test. You really need the practice tests to get a feel for how the actual test will be. Testking is truly king of all test guides.

Written Clearly
I like the test GRE free by Testking. It's written clearly and it wasn't too expensive. It has several samplings of test, whole tests, in the back. Furthermore, it provides examples of everything. I'd say more, but I need to take the test before I can say candidly how well the book prepared me. This book is great for refreshing you on the subjects, but find another source for taking actual sample tests. The language is very easy to understand. The book is written in a comprehensive way, I would recommend it to anyone.
