Hi Everyone on SDN. I am starting to study for the biology section of the MCAT. I am mainly using the Princton Review book and the Exam Crackers book. For those of you who used either of these materials can you please tell me what to actually be memorizing from the materials or just simply understanding at a functional level. I could really use some guidance on exactly what I am supposed to be doing with these books. The Princeton Review book seems to be more detailed and almost too much to memorize but maybe that is supposed to be my goal. Please offer any suggestions that you have.
