Great GRE Tutoring
This is a great book that teaches some strategies to answer the questions on the GRE tutoring. It is much more useful than the books by other companies, although there are some minor errors scattered in the book. The online practice tests are difficult, but that will push you to study even harder and I got a higher-than-expected scoreThis book is a nice overview and preparation material for the GRE, especially because of its online companionwhich basically means being able to take genuine-looking GRE tests.

I Am Happy
The book itself contains lots and lots of information and tips as a great GRE tutorial.It does contain specifics for the verbal, cuantitative, and analytical sections, as well as what to do, how to pace yourself, and what to focus on according to your goal score for each section and overall desired score. I used Testking more like a crash course but it could probably be used for a longer period of time as well. Also, the book material is light, which makes it easy to carry around. I am happy I bought it.

Great GRE Starter
Overall, this is a great starter book to prepare for the GRE. It has lots of great tips on how to prepare, but it was insufficient in its explanations of the sample questions. The sample questions in the verbal part was well put together, but when you get to the math part, the sample questions offers little explanations how they got the answer. A few sample questions in the math section. This should be the only book you use to study as GRE tutorials...it's just good as a starter book. Thanks to Testking

Sufficient Practice Problems
I felt the book did contain sufficient practice problems. The problems provided were out of context of a real GRE tutors and were in a more explanatory setting. There was a lot of test taking skills explained. I felt most of this information could have been easily condensed and dragged on.The most useful part of Testking was the information about how the exam works and how to prepare for each section. Practice tests were nice also. I feel that it is a good supplement to other study materials.

Good Luck To All
I feel that Testking GRE tutoring is the quint essential tool in a student's preparation for a GRE test. It gives you great advice on all fronts allows you to access two full online tests on their website and has a complete list of problems at the end of each section. Its section dedicated to Analytical Writing is specially helpful for those who haven't written critical and analytical writing in a while. It is actually quite useful and intellectually stimulating even after you've taken the GRE. Good luck to those preparing for the test.
