best majors for student who wants solid backup route in case they change mind on Med School?

For the OP, I started college thinking I would be a medical doctor. By my sophomore year, I was no longer interested in becoming an MD. A lot of college students go through this and make it out with solid careers. Of my friends who started pre-med and changed their mind, most of them started re-tailoring their degrees after sophomore year towards a different career. You can do that by changing ECs, looking for internships, adding a 2nd major or a minor, etc. The prereqs for med school overlap with other health care related grad programs. What it says on your degree isn’t the be-all and end-all. One of my friends has a biochemistry BS and got into architecture school - she just decided that’s what she wanted and focused on making a good portfolio.
