She gets one hour a week of class time with that teacher


AOPS online courses have only about 1.5 h / week live sessions - via special chat online (these work just fine). Others say that instructors are responsive outside the live sessions (i have no first hand experience with this in particular, though). So, if you are looking for more instructor access, this may or may not suit you. Your DD can try a course and cancel within 3 weeks or so with no penalty - best to see firsthand.

AOPS has Calculus course (well, it also has 'Group Theory' course), and judging from what I see in other AOPS courses, I'd guess that it is way more rigorous than regular AP Calculus (granted, the AOPS version does not have the AP label which would be valuable for the HS transcript.)

AOPS Online School is now accredited (by the Western Association of Schools and Colleges), so there should not be a problem with course certification.
