The tips begin at a different place in each module. The advice moves along with the stages of the course.
Molecular biology content review should follow after biochemistry. However, too much memory work late in MCAT review can lead to a bad outcome. While making your way through the foundation physical sciences, begin a study cycle in molecular cell biology that continues through to physiology. Start early and keep at it. Work to get your MCAT book practice items in biology finished before biochemistry is done. This is a long first cycle to make you strong in molecular biology and physiology even before careful topic centered review later in these topics.
