The main topical progression represents one long cycle in MCAT review. However, you should also perform epicycles. Epicycles are shorter comprehensive cycles. Perform one at the beginning of MCAT review to prime and structure your knowledge base, several in the middle to fortify and maintain your progress, and many epicycles at the end to get yourself into exam-day shape. An epicycle can be as simple as skimming your MCAT books from start to finish or reviewing the presentation slides of the course from beginning to end.
