AP Physics online?

Because of a scheduling conflict at DS's school, he cannot take Physics, as planned. Does anyone know if there is an on-line AP Physics option (homeschoolers perhaps?). How do you deal with the lab portions? I know absolutely nothing about on-line courses. Are they accepted by colleges (and how do you go about that)? He's already carrying 8 IB classes this semester and it is going to be really hard to stick in a 9th advanced class and still do his ECs (but he'll have to manage).

HSLDA (Home School Legal Defense Association) Online Academy offers AP sciences including AP Physics. We did not use their classes, but HSLDA is very well-respected in the homeschool community. Classes started 8/27, but you may still be able to get in. An online AP course is recognized the same as a brick and mortar AP class.

Also aphomeschoolers.com. Very reputable.
