Greetings! I'm in the process of making a career change and going back to school so I can hopefully get into Medical School. This next semester I am taking my first Biology (Gen. Bio I) and Chemistry (Gen. Chem I) classes and I'm a bit nervous. I don't remember the last time I took these classes, and I know how critical it is that I score well if I want to get accepted. Are there any study materials or books I can be studying to get a head start? Thanks!
