retake physics/upper level physics?

I got the physics 2 credit from AP physics C E&M in high school but not physics 1. So I know I'll definitely have to retake physics 1, but I'm also seeing some schools don't take AP credit for physics at all, and instead require an upper-level class. Does anyone have experience with taking upper level physics when you didn't intend on it? The idea of physics 3 scares me (but it might be doable as a math major I guess). Or is retaking physics 2 the way to go?
