AoPS Online is the online school of Art of Problem Solving, aimed at strong math students in grades 5 to 12. Students join weekly live classes or self-paced courses in prealgebra through calculus, number theory, counting, contest prep (AMC, AIME, olympiad), Python and physics, with weekly homework. The site also hosts Alcumus practice, free Math Jams and a large problem-solving community with forums. It is accredited by WASC. Beast Academy, for younger kids, is listed separately.
Our take: A strong fit for a child who loves hard math and wants contest prep; a child who is behind in math needs something gentler.

Does it work?
The maker's own claims only: it notes many US Math Olympiad team members are alumni. We found no independent study of learning gains.
