This is a great set to study from. Just to clarify as the description of this item is not clear, you will receive 5 study books in the package. A chemistry, organic chemistry, biology, physics, and verbal reasoning study manual. They come in a convenient box to hold them in and it also includes a full length, separate practice MCAT. It is cheaper to buy this box set than the individual books and it includes the practice test, which is a great resource to have. Also, this is the newest edition out there. The last edition (7th) is from 2007 and therefore a little dated where these ones are from 2013 and therefore up to date.
As for the books themselves, I've only gone through the physics and organic chemistry ones so far, but they are actually kind of fun to read! They include vivid, color pictures that describe the concepts incredibly well. Usually, I just skip over complicated diagrams and pictures in text books, but the ones in the manuals are very helpful and easy to understand. These manuals also do not read like traditional text books. Writing is broken up and only the essential, need to know ideas are included to avoid waisting your time learning topics that will not be found on the MCAT. However, if you are not familiar with some concepts and ideas than these manuals can make you a little confused as the author kind of assumes that you have a general knowledge of what he is talking about. So if you have never taken a physics class before or remember barely anything from it, then these books might confuse you as they skip some fundamental points.
I did a lot of research on whether to go ExamKrackers or Kaplan Review for MCAT books, and I can say I'm glad I bought this set. I'll be sure to update this review once I've taken the MCAT to see if these books really helped me.
