How difficult is the Science on the MCAT?

The good news is that the Science on the MCAT is not very difficult. Most students spend way too much time studying the Science and not enough time practicing passage-based questions. Most MCAT questions do not directly test your knowledge of basic Science concepts or your ability to make simple calculations. Instead, they require you to apply your knowledge and to interpret new information presented in the passages to answer the questions.

The bad news is that the Science may not be very difficult but there is a LOT of it. The MCAT covers nine semesters of introductory natural sciences (one semester of Biochemistry, two semesters of Biology, two semesters of Chemistry, two semesters of Organic Chemistry and two semesters of Physics) and two semesters of introductory behavioral sciences (one semester of Psychology and one semester of Sociology).
