Have you worked/volunteered in a hospital or other patient care setting? How do you know you want to be a doc? Didn’t see this in your EC list.
My wife is an MD who went to a very highly regarded med school. We have discussed college issues ad nauseam, as we have one kid headed the medical route. Our general agreement, and the opinion of many of our friends who are MD’s, is medical schools don’t care much where you went to undergraduate, they do care about how well you did, your MCAT score, and proof that you know why you want to be a doc (this is particularly important). So I wouldn’t stress about it.
If you have a teaching hospital close to you, I’d try to get a connection there. I’m sure lots of residents could give you some great advice on colleges, majors etc.
