It’s mostly online, but there are also learning centers at which you can take classes. I believe the a lot of users are home school students. Many are students for whom their school’s math curriculum is too easy. AoPS is used heavily by students competing in things like the math olympiad. In addition to math, AoPS teaches two computer science courses in Python, which are roughly equal to first semester of college computer science. The teaching is both an online lecture and reading from a textbook, as well as office hours and supplmentary videos. There is also homework, which is graded and gets long responses, of the type that usually takes the grader 10+ minutes to write. Source: used to grade Python homework for AoPS; I should not be considered speaking for AoPS and I may be incorrect about some of this as I never was a student.
