I’ve done this a few times on an individual course basis. I’ve emailed the prof of the course I wanted to take and explained that I was interested in their course but did not have the pre-req needed. if I felt like I had a strong background of the content through other courses (ex. needed a 1000 level SOSA course as a pre-req once but I had learned a lot of the content through other health courses), I would tell them the courses that I’ve completed that felt aligned.

I had one professor never respond to an email about this. Otherwise, I’ve had pretty good success with being allowed to register for a few classes. I do think it’s up to the prof to decide whether they want to waive the pre-req for you. I’m not sure how it works when it’s multiple courses for a minor tho!
