So I've done this before and they let me take the course but it is not counted towards your elective. For me the course shows as a not assigned to a requirement but it counts toward the C.A. and S.A.. So if it's a bird and you want to take it for fun like I did you can always get permission it just may not count. I took Bio 1m03, just for fun. Defiantly talk to a counselor.
