For UC, distance education offerings, PERIOD, probably won't qualify as a-g credits in some particular areas. No matter who you take them with.
The only solution to fine arts and science credits that I've found will work-- and this goes for homeschool or virtual school students-- is to take those classes during a summer session at a regional/local college or community college. That way you have an OFFICIAL statement that you've completed a laboratory/studio experience which is the sticking point for UC in particular.
Yes, they are also squicky about natural selection in the sciences-- but that one is more easily dealt with via SAT II subject testing or producing a course syllabus.
It's that lab/studio component that is hard to meet. It has to be expert instruction (so not parents) and it has to be rigorous and specifically tied to curriculum at the secondary preparatory level (not science fair or art contest-- but INSTRUCTIONAL).
