undergrad majors

None specifically. You can take the pre-med requirements alongside almost any major (except for a few majors with voluminous non-overlapping major requirements that leave insufficient elective space for remaining pre-med requirements).

If you want the most overlap with pre-med requirements for “convenience”, the likely choices are biochemistry, then other biological science. But job and career prospects specific to those majors if you do not get into medical school are not great.
