Lol! that's us, Dottie. This is that flow chart I found a while back. That would be for the 6th grader allowed to take 7th grade extended math, which I think they also refer to as 'pre-algebra'. That is what we are shooting for, although I think Algebra would be a better fit for Ds, since he is already doing well in his online algebra.
At least they look at a variety of criteria, I can't say they don't do that. Unfortunately this is the year that ds really got B-ored with math at school, and has around a B+, not an A average, so that will not probably look 'perfect' either.
Of course they emphasize that the class moves really fast, but otoh, if a child already knows the material I would assume it wouldn't feel very fast.
