I agree with @thumper1
Colleges do not publicly report the MCAT scores of their students. So you’re not going to find that information anywhere.
Also MCAT scores do not say anything about the rigor or quality of an undergrad pre-med education at any given school. A MCAT score is more a reflection of the student’s self-discipline & diligence in preparing for the MCAT and their native intellectual ability than anything else. The MCAT does not test the knowledge learned in pre-med coursework. It tests how well the student can take that knowledge and apply it to novel situations.
BTW, med school pre-reqs are all introductory level classes that you can find at any community college in the country (except for biochem). Students who take their pre-reqs at CC can and do score very well on the MCAT.
Since the majority of students who enter college as pre-med do not persist on that pathway and will never apply to med school (and not because they are not intellectually capable of doing so/aren’t able to earn good grades, but because the path to becoming a physician is very long, tedious and requires jumping through tons of hoops), I would urge your son to look for a college that offer him the best combination of fit, opportunity and costs.
Fit because happy students do better academically.
Opportunity, including the opportunity to explore other majors and other careers, because the odds say that your son will find some other career path that is NOT medicine during college.
Cost because medical school is hideously expensive and pre-meds need to minimize any undergrad debt.
RE: Research is the least necessary EC for med school applicants. High school students and their parents often greatly over-estimate the value of undergrad research in developing a med school application. Med school adcomms in a national survey ranked research as being of “medium” importance when making decisions about who to interview. Patient-facing ECs (clinical experience, physician shadowing), community service with the disadvantaged and leadership roles in their activities were all ranked as having the most importance by med school adcomms.
N=1. One of D2's best friends from HS attended Carleton and later went to med school. She did just fine in her application cycle, receiving multiple acceptances.
