Does anyone here know any good online math courses? I want something that covers topics in-depth and that is around highschool level in terms of difficulty. I want it to video-based and would rather it be live than pre-recorded. I know this isn't what usually gets posted on this forum but if anyone has any recommendations I'm gladly willing to hear them.
I might be biased since I've only ever really done Kumon and Mathnasium as a child and those aren't the best options if you want in depth and higher level difficulty, but I've been doing spirit of math for a while now and I think it's a really good program and that you should consider taking it? They have courses from kindergarten to 11, 11 being equivalent to about a first year or second year university math course (according to their website) and I think they have really good problems (lots of experience just from doing these problems) and teach you really useful skills.
I wish this was sponsered but it isn't lol
tl;dr Spirit of math offers good courses (right know it's online but if there wasn't a pandemic it's in person) and all you need is like a B in all subjects or something like that to get in. Good topics + experience. There are grades but they don't matter :)
do AoPS courses + Khan Acadamy courses if you really wan't a strong foundation, and Kumon is really good as well
AoPS, or you can contact private tutors which I believe are best. AoPS stands for Artofproblemsolving.
