The book you are referring to is available from Amazon and BN but I have read the description on both websites as well as TPRs website and they both state the following:
"MCAT scores are a critical factor in the ultra-competitive medical school admissions process! Cracking the MCAT brings you proven techniques from the test prep experts that will help you score higher on the exam. Plus, it includes the most up-to-date information about the MCAT CBT (computer-based test) format.
In Cracking the MCAT, we'll teach you how to think like the test writers and we'll give you
-Hundreds of practice questions in the book and exclusive free access to practice tests online
-Simulated MCAT passages just like the ones you'll find on the exam
-Substantive practice tied to every concept reviewed, followed by detailed solutions
-Special sections on MCAT essays and a review of essential mathematics
-A thorough and systematic review of all science and verbal skills you'll need for the MCAT
All topics in the physical and biological sciences are presented with sample problems, labeled illustrations, charts, and diagrams. Our practice questions are just like those you'll see on the real MCAT–but with detailed answers and explanations for every question."
I think you should just call up TPR or chat with someone on their website to figure out what exactly comes with the book.
