Some people who have taken TPR course, will you tell me about the materials in detail? I have heard there are 3 subject books and 2 workbooks, but how big are these and how useful are the problems in the workbooks? Is there any other material other than these books? What about practice tests, do you get access to any other practice tests except for the officially proctored tests? Did you feel that the books were too large and specific to get through, or was it a good amount of material? Overall, were you happy with the materials? Thanks. Oh, and did you feel like the TPR practice tests were much too difficult. By this, I mean, not were they harder than the real MCAT, but were they too hard to be helpful for the actual MCAT. As in, not an accurate depiction.
