Update: talked with the advanced geometry teacher, underwhelmed by the curriculum. I don't think it's that advanced. It was consistent with our impression with the advanced algebra that my DS took at the same middle school. It's better than the regular track, but still very basic.
DD wants to maybe try the classroom for a couple of weeks at the beginning of the school year (she has two weeks to switch to online).
I will find out how our district views AoPS courses. I think DD needs this no matter whether she does the online regular geometry, or the in-classroom "slightly better" geometry.
