I took real college physics without any background at all. (One year of bio and one year of chemistry in high school). It was difficult but not impossible. However despite my lack of background, I’m pretty good at math and spatially minded.
However I wouldn’t recommend taking two AP classes in one year with no high school equivalent class preceding them. Too much danger of being overwhelmed.
In our school Physics B replaced honors Physics, it was fine to do it that way. It didn’t assume any prior knowledge. I don’t know exactly how the new Physics 1/2 curriculum is going to be handled. I had one kid who would have happily doubled or tripled up on AP sciences - the other one was better off taking them one at a time.
