Online AP Courses

I was thinking of doing an online ap course in my junior year (next year). My school doesn’t offer any AP courses and I don’t think it will be super hard to focus on the computer.
I want to take AP Bio, AP Spanish, and maybe APUSH. Please let me know if you have taken these courses online, where, and your experience with them.

Pricey, but worth it. UCscout offers an APUSH course for $169 per semester (teacher-led).

Give me a price range and I can probably help you a little more (-:
