M. Yau is right, the quality of this book seems sub-par. You can sense a difference between what the real tests questions feel like versus the ones created for the book, and the explanations of the answers get very lazy as the book goes on, supplying no real explanations. After I while I didn't trust whether I was getting an accurate barometer of a real LSAT. Also there are several typos and mistakes in the book, which make you doubt what you're reading sometimes when you come across a stumper. I'm very frustrated and I'm about to drop this book and go buy a new one.

the book gives 2 actual exams and 3 "lsat-like" exams along with practice "lsat-like" questions in each of the three sections. when you go through the "lsat-like" questions, you can tell there is a difference in the quality of the problem sets and questions. but much worse than the fact that the "lsat-like" problems are not comparable quality to the actual tests, the answer section gives very poor explanations for why one answer is better than the others, except to say that it is correct and the others are not.

the practice tests that are not real also fall short of providing a conversion from raw-score to actual lsat score, so even after you spend a full two-three hours taking a practice test, you don't really know how it would have been scored.

i would recommend buying actual lsat tests to practice off of or the kaplan books that have better explanations for the answers.
