So I finally decided to start reading my TPR biology book since I have a very tenuous grasp of physiology, but the book is so badly written that I am learning nothing. There is a paucity of diagrams and the diagrams that are available are poorly labeled and do not help make any of the material clear. So, now that I have 2 weeks till my MCAT exam, I have two options: I can either keep reading the TPR book or I can switch over to my EK book. The EK book is far more easier to read, but I feel that it's lacking a lot of detail. Is EK biology sufficient? I'm scoring 12-13 on the BS right now, but I feel that I can solidify it to a 13 if I just get a better grasp of the material (and finally review organic chemistry rather than making educated guesses).
