If others can comment on the amount of support (e.g., counseling, ECs, tutoring, etc.) the schools on your list offers premed students, that’s would be very beneficial to you. But undergrad bio is undergrad bio is undergrad bio, etc. at pretty much at any college, especially in lower division (LD) premed reqs. Profs just tend to teach LD bio, chem/ Ochem, physics, etc.; not LD bio, chem/Ochem, physics, etc for the premed student or as MCAT prep. Premed success is largely on the student’s shoulders, not the schools. And you don’t have to be bio major. You can major in anything that interests just as long as you do well GPA wise. Pick the school where you believe you’ll fit in the best and can graduate with little, if any debt. Good luck.
