Good UC approved online high school summer physics courses

I am looking for a physics course that I can start now and complete over the summer for credits. I am a junior in high school and am trying to make my senior year less packed, so I am hoping I can get physics out of the way. Are there any physics courses out there designed for high school students that are UC approved and give the option of starting whenever?

Check out http://www.ucscout.org/ , only downside is that they have a lab requirement and I’m not sure how that’d work. Email them!
