Do I need to pre-study before medical school starts?

I've been out of school for two years now and med school starts next week. Do I need to do any pre-studying? And do the concepts build off of each other? I'm hoping instructors go over foundations and such beforehand. I'm especially worried about anatomy & physiology, since I've never them.
