The problem is, my classes at the university are painstakingly boring, like the classes at my high school had been.
Junior college, or 2nd / 3rd tier state school? What classes are you taking? What kind of course load (how many hours)?
For physics, you're going to need a lot of math. You ought to be able to take a placement test through the dual enrollment program to get you into a math class that's somewhat challenging; the junior college near me goes up to DiffEq. If you already know Calc I, have you taken a calc-based Physics class? If you don't know Calc I, and the issue is pacing (class moves too slow), and you can't get compressed scheduling (I can get 4-week classes that cover 16 weeks of material, for instance), do the math through EPGY, which is all self-paced.
Are you already doing the MIT classes (here:
http://ocw.mit.edu/courses/physics/) as part of your homeschooling? Did the Quantum Physics classes there (undergrad and/or grad) keep you busy?
