Most Powerful Tool
Testking's ISAT book is by far the most powerful tool that you can have in your arsenal, as you prepare for the ISAT. It teaches clear and easy symbolization techniques, helpful places to look in making deductions, and the most effective ways to tackle different kinds of questions. I am much more efficient and scoring near perfect. This book raised my practice LSAT score ranges.The more tests you take, the more your comfort level will grow and the higher your average score will become.

Extremely Comprehensive
This is the best ISAT book which is extremley comprehensive in every respect... But if you are smart enough to begin your ISAT preperation a few months ahead of time--and are willing to work --then this book will do the trick.I bought about 6 books to study for the ISAT, and each book has a different approach. The Testking book really has the best guidance, and information.These are short and to the point and every logical step, and inference is well-explained. There is a lot of information to retain. It is worth the money.

Highly Recommended
If you are at all worried about the ISAT, I highly recommend Testking's Best ISAT book to you! I think this book was very helpful; the exercises and explanations help you master all the types of questions the ISAT throws at you.It should be only one of your tools in ISAT training.This by far, was the best resource I could have invested in for the ISAT. I can't imagine having taken the test without the aid of this book.I recommend this book to anyone who wants to get a good LSAT score.Many thanks.

Get It Done Quickly
Words cannot describe the benefits the ISAT books provided me with from TESTKING.I have read through many books...spent many hours on sections. After I read this book I was trying to think back at how I attacked ISAT and I began to wonder how I even accomplished them.This book tells you how to approach a question and set up diagrams effectively--and to get it done quickly. They use real ISAT questions...a lot of them. The explanations are easy to understand, detailed, and thorough.Thanks so much.

Good Teaching Source
I wrote the ISAT recently. I bought a miilion prep books! Testking's ISAT book is a very good teaching source. It describes the problems well. In my opinion, the best preparation for the ISAT is replicating the real test as closely as possible. I credit this book with helping me to move from the 93rd in initial testing to 97th percentile on the actual exam. I did all my own preparation, and did not pay for a course of any kind.Without this book, I would never have done that well even with the easier section.
