Medicine or biomedical science?

There is literally no point in applying to a medicine degree if you don't want to be a doctor. The entire point of the degree is to train you to become a doctor. While yes you can do other things after a medical degree, that's not the purpose of it and anything you could do after a medical degree that isn't medicine you can do after doing another degree (either any degree or a specific degree, depending on the intended outcome).

If you know you don't want to pursue a career in medicine, skip the medical degree and do another degree of interest.
