Hedwig and titan,
No. You don't need anything else. The only thing extra classes might get you is some familiarity with the terminology that diff classes use. I took biochem b/4 getting to med school. After two weeks in our first quarter we had covered all of the info I learned in a semester and then some.
My advice to you is to enjoy your time off from here on. Travel, sleep, relax, read things not pertaining to med., because once you start, you really never get a break. So enjoy your time off. Some would say take anatomy, however, undergrad anatomy only gives you names of muscles arts, nerves, veins, origins and insertions, and in med. school you need to know those, but, more importantly you have to know how they all relate to one another and their associations. It is an entirely diff way to think about the subject so if you really want to do something look at a Netter Atlas and learn some names, but, I can't emphasize this enough...HAVE FUN WHILE YOU CAN.
any other questions let me know.
