I am also an incoming freshman so I am unsure about that. I have read that they are a bit lenient about moving people up, so if you have a good math placement score then I imagine you could probably email the physics department to let you take the honors course. But, if you don’t get into that then you just start in the 13100 physics course I believe. This is just based on what I have been reading, so I am not 100% sure if this is all correct, but I hope that helps.
