For me, I think that brilliant[0] might be one of the vest resources out there! (no affiliation)
Their "learn to think" tag line is totally true, and after trying to learn sciences and math by myself (my formal training is in liberal arts so...) by reading text books and such, brilliant was absolutely brilliant!
Instead of throwing at you a bunch of facts and formulas and whatnot, they aim to teach concepts with real-life applications and thus taking you from what you know to the thing that they are teaching (something truly rare in western fact-based education)
Anyways, I can't recommended them enough! Good luck!
