For any given college, you need to add up the following:
A. Courses/credits needed to complete your major (and minor or second major, if any).
B. Non-overlapping (with A) courses/credits needed to complete the pre-med requirements.
C. Non-overlapping (with A and B) courses/credits needed to complete other degree requirements (e.g. general education requirements at the college).
If A + B + C <= the total number of courses/credits that you can take within the expected time there (generally 8 semesters), then it is doable.
