Taking online classes for high school credits?

<p>Any one have any experience, next summer I'd like to take Pre-calc and French III so I'll be able to take AP french in Senior year and Ap calc Ab and Bc in Junior and senior year.
I'll have to talk to my guidance councilor to see what courses they accept (if any)
But I happen to have several questions about the whole thing
Do they grade these online courses? Like will they go on my transcript?
And does anyone have any experience with this sort of thing? Is it harder/ easier then a classroom course?</p>
