Well, there's a Future Physicians of America club at my school, and I'm not in it, but I have friends in it. They do fundraisers to raise money for field trips, and they often attend medical conferences. They also do a special unit that focuses on getting into medical school.
I used to be a member of a medical club outside of school called Medical Explorers. They met at a local medical center weekly, and were advised by a retired doctor. They had speakers at every meeting, and the speakers were from various departments at different local hospitals. We also took a field trip to the Stanford Laboratory and got to look at cadavers
. It was really an exciting experience.
Hope I helped!
