What To Do With Time Before Med School?

Hello,

I am a rising Junior in undergrad who was accepted to my school's early assurance program. With this time given, I was planning on pursuing of course higher level coursework in the sciences + public health as well as try out other hobbies/clubs and volunteering. I am also planning on starting some research with my the medical school, if that's valuable.

But, I was wondering what some people might do in this situation before going off to med school. Are there things that some med people wish they did before they matriculated? Are there things that I could do right now to help ease my workload or enhance my experience in medical school?

Any advice would be greatly appreciated.
