Glad I started studying the LSAT with this book.

Easily the best explanations of the games that I have read. Some exercises about identifying game types are a little tedious and unnecessary, but overall the book is excellent.

This book is very useful info on proper diagramming techniques
because it provides explanations throughout the chapters help with learning the application of techniques. In addition, the organization is excellent in this book. The drill explanations are detailed.

I'm a nerd for including test prep in my library, but the powerscore books are that good. If you take the LSAT you need to spend a lot of time with this book.
