The book is 16 Chapters of Physics. It has discrete questions followed by passage-based questions(like the MCAT) for each chapter. This book is about concepts and there aren't enough passage-based problems to really give it a MCAT feel. I chose this book over Examkrackers because I wanted that in-depth coverage. I only wish it was in color.
I agree with the above - I've just started using this book myself, and there really aren't that many passages, compared to other books that are out there. However, I'm finding it extremely helpful so far. Each chapter is explained in simple and manageable terms, and the problems at the end work you up from very simple to a few passages; I really strongly dislike physics (I'm even a little scared of it) and I've been finding that the way this book is set up gives me some much-needed confidence.
I recently purchased NOVA Biology, although I've yet to start reading it. I'm planning on getting the Physics and Chemistry as well. They seem to be somewhat comprehensive, and that's what I'm generally looking for.
