I recommend molecular bio, genetics, and virology. Take a bio class that will force you to read REAL research articles... It will teach you to search for vital info and not get lost in the madness. This was the case for my virology class. I believe it was an upper level writing intensive bio course that was an elective. As for genetics and molecular, they just give you a feel for how the body works and the mechanisms that we have in place to protect us. It's fascinating really. Did you know we have heat shock sensors??? LOL no im not in med school.... Yet
