Adcomms really, really donât care what major an applicant has. They only care that applicants have completed the required pre-reqs. (Assuming the specific med school still has pre-reqs. Many med schools have moved to competency based admissions. UCLA, UMichigan, Duke, Creighton, Einstein, USC, etc. See MSAR for the full list.)
Having an âout of the boxâ major wonât help an applicant stand out. My daughtersâ med school classmates had a wide variety of undergrad majors including forestry, Italian & enology, theology, music theory, physics, mathematics, gender studies, English lit, Spanish, communications, sociology, history, business, computer science, and various flavors of engineering, as well as the more common biology, chemistry, biochemistry, neuroscience, BME, and public health.
BTW, the allied health sciences are typically a poor choice for most pre med hopefuls. Even adjusting for the fact the allied health science majors have lower average MCAT scores, allied health science majors still have the lowest acceptance rate into med school of any group. (see: https://www.aamc.org/media/6061/download?attachment)
Majors with highest acceptance rates are humanities majors and math majors.
Business may not be especially useful for future doctors. Today most physicians are salaried employees of large group practices or corporate management groups and do not run their own businesses. Solo and/or small group practices are going extinct left and right.
Also students who are enrolled in the College of Business need to check to see if their university will allow non-arts and science majors to cross-enroll in CAS classes. (Some will; some wonât.)
