We discussed wave functions, probability, fermions/bosons, did calculations for particle in a box, the Schrödinger model, and went just up to deriving the hydrogen atom. Nothing super fancy, but it was one heck of an experience!
Also your project is incredible btw, maybe look into robotics too.

Yeah, that's college level stuff, it's pretty fancy for high school, you go to a nice place :)
