I thought this book would be much more helpful than it actually turned out to be. The claim that they have answers and explanations to 50 sample questions, while true, is horse hockey. The answers to the sample questions simply reference the appropriate Model Rule. Don't waste your money on this book. Instead, I recommend that you get hold of the two-box set of flash cards (published by Emaunel, I believe) and spend a month or so going through them with a copy of the Model Rules in front of you. That strategy worked well for me and I scored a 120 on the exam, which is high enough to be admitted to any jurisdiction in the U.S. I have friends who waited until they attended the Bar/Bri review course to study and a large number of them didn't score high enough to be admitted in their jurisdiction of choice and will end up taking the exam again.
