Thanks for the reference to the Northwestern online class. I will take a look at for future needs (one of my younger kiddos is super mathy and math acceleration is getting more difficult to come by around my geographic area in middle school, even in the private schools). As for DD, I met with her teacher and discussed DD's desire to do online geometry. Cut to the chase - the teacher said she would completely support DD's move into geometry class right now, in school, after seeing her in-class performance over the past several weeks. I am thrilled, as I had already heard from one HS that they would not accept AoPS for credit even if my daughter passed the placement exam! I still bought the AoPS books for home support for my daughter.
DS11 is almost finished with the AoPS Intro to Geometry book. He has self-studied the material with the solutions manual. We tried EPGY's Geometry course but at the time they had quite a few difficulties so we requested a refund. (DS had taken 4-5 previous EPGY online courses and all was great.)
DS11 has only gotten "stuck" a few times and was able to either ask on the AoPS forum or get a teacher at his school to help him. Only negative we have seen is that NC does not recognize the course (either online or manually) so DS will need to repeat Geometry for HS credit. It seems his new school will let him use Northwestern's online Geometry course and it will work for NC.
AoPS does seem to be more difficult/thorough than EPGY.
