At first, this books seems good - helpful, friendly, and complete. However, as you go through the course, you discover that the book is filled with errors, and important ones at that. The most typical error is that the explanations of the problems often seem to refer not to the question in the book, but a question from a previous edition of the book. This causes great problems, especially considering they place the answers to the practice problems in these explanations. Secondly, the books "friendly" tone gets old fast. Statements like "Reading comprehension tests your ability not to rip up the test into little pieces and fling them at the proctor," are sometimes funny, but their repetition reveals not the absurdity of the LSAT, but that of the writers of this study guide. Finally, the books seems geared to those who would like to receive an "average" score (approx. 150-155). If you want to do very well, you might want to look elsewhere, or at least buy supplementary books. This one will not get you there alone.
