Definitely A Better Source
Overall I would have to say that Testking is definitely one of the better ISAT logical reasoning guides.It tries to show you techniques that are at least fairly consistent. In addition, they do a fairly comprehensive guide of building up a basic foundation of likelihood of actually coming across those particular types of questions. What I found particularly helpful. was their updated content which is available for free online at their webpage. I highly recommend going there to get the latest info on content and style.

Greater Improvement
This is the single best product I've found for ISAT logical reasoning section on the lsat. I'm sure a greater improvement would have been possible, if I had a chance to perfect the methods in the book. One of my friends as a matter used Testking for a longer time than I, and the logical reasoning section went from being his weakest section to his strongest, eventually achieving near %100 accuracy.Testking truly gives realistic strategies for success.It is patient, clear and an organized product.

Enhanced Problem Solving Techniques
I am taking the ISAT tomorrow, and feel quite confident with the skills regarding the logical reasoning ISAT I've sharpened .Testking guided me in learning the necessary information, and necessary coursework. When comparing the problem solving techniques, I found the techniques to be "cleaner" and more accessible for the global and localized questions. Additionally, the indepth review of answers helped tremendously in learning. I take the test tomorrow, and feel confident in my abilities. Good luck to you as well.

Great Score Boost
I join in praising of Testking's guides. It provided a great score boost for me, since I took the first practice tests by myself after reading other books. The book has both technical knowledge and general advice, that were very helful and it uses real ISAT tests. I used the strategies that I learned in it, and it really helped me when I took the real ISAT. I also highly recommend Testking's ISAT Logical Reasoning sections that will help you to improve your score in this section.Well Worth The Money!

I Am So Glad
I used Testking's materials when preparing for the ISAT and my practices scores increased an average of 11 points once I had mastered the Logical Reasoning Section. Unless you are a natural with this section, I highly recommend you use this book to learn strategies to attack that section. It will teach you how to identify which "type" of questions you are dealing with, and then you will learn the various strategies specific for each type.This book removed all the mystery of the logic games for me, I'm so glad I had it.
