There is nothing that is as close to the real MCAT as the AAMC practice exams. I took several tpr exams with the class, but the only kaplan test I took was in that big red book you can get at any bookstore. I think these tests are good practice to help you learn the material, but on the MCAT you have to use the passage to answer questions a lot more than these tests (except AAMC) make it seem. They make it seem like you must do a ton of memorization to succeed like in your Bio class, but you must be able to do critical thinking and apply information you are reading for the first time, which is why humanities majors score higher on all sections.
