I'm a sophomore nutrition major and I want to go to med school or maybe just PA school. But either way, I want to make my summers productive in terms of learning more about medicine. I have great book on pathophysiology that I've been reading, but there is just so much information that it's difficult to retain all of it. What are some good books I can order or even online courses that I can take to become more savvy about medicine/disorders/anything related to the medical field??
