The Ohio State University has a “math biology track” in its math major:

It does not automatically include all pre-med requirements (e.g. organic chemistry, physics), but those can be added in elective space. Since you will have completed most frosh/soph level math courses before high school graduation (based on your other thread), you should have plenty of elective space in your four year schedule.
