My school has:
- Biochemistry
- Biological Science
- Biomedical Engineering
- BioResource & Agricultural Engineering
Pick which ever major interests you, where you think you can get a high GPA and will be a good stand alone major as a backup in case you do not get into Medical School.
No specific major is required to go to medical school, although you will need to complete a set of pre-med courses.
About half of applicants and matriculants to medical school major in a biology major, probably out of convenience (due to overlap between pre-med courses and major requirements). However, half major in something else (where the overlap is less or none, so the pre-med courses are taken in the out-of-major breadth and elective space).
