^This is absolutely true based on D’s experience. I do not have any others.
I serve as an occasional part-time admissions interviewer for several med schools (however, I am here as a parent), and I heartily reaffirm that the school does not matter as far as I have seen. Many stellar applicants come from state flagships, liberal arts colleges and research universities alike. It is all about the applicant, not the school.
Good pre-med advising should suggest research, volunteer and shadowing experiences. Major does not matter. Dual or difficult majors do not matter. If your school doesn’t have good pre-med advising, find materials online from other schools (JHU, Amherst) and look at med school websites.
The computer programs that analyze AMCAS applications to decide to offer interviews use GPA (BCMP), GPA (other) and MCAT. There is “holistic” consideration of distance travelled, challenges overcome. Interviews matter A LOT (basically can I see you taking care of my mother?), as do essays and fit with the specific medical school.
The only situation to be somewhat wary of is going to a very small college close to home, without substantial experience of other cultures/geographic areas. This could limit an applicant, due to lack of exposure to diversity, so if you find yourself in such a school make sure to do study abroad/travel programs to counterweigh that.
Otherwise go where you will be happy and where you can afford it. Major in what you love. Get a good GPA, MCAT, research experience, volunteer and shadowing experience. Like to help other people and show it. If you are not admitted first cycle, do not give up, try again after strengthening needed parts of the application.
In a nutshell: go somewhere undergrad that is inexpensive and where you can get a good GPA.
Flip the coin if you have no personal preference. The personal preference is the ONLY criteria that is important at this point… Forget about Med. School, too early to think about it.
