@konchelle think about what you want to do with your math/science major. Chances are you will be going to some sort of graduate school. My advise would be to look up what those schools require and see which major has the requirements that most closely align with what you will need for graduate school.
This isn’t from SLO but we found it to be a very useful link if someone is interested in going into health sciences.
