What are the best (free) math resources out there?
EDIT: Thanks everybody for the suggestions! You've been great help to me.
I'm getting prepared for my computer science degree in college but pretty behind in the related classes. What are the best resources out there? Preferably in English as my native language resources are shit at explaining the basics.
I'm currently studying in Khan Academy but was wondering if there are somethings I'm missing out.
NOTE: I am NOT in college yet. I'm trying to get in college now. So the stuff I'm looking for is high school stuff.
Are you worried about getting in or are you worried about what you'll do when you get there? What I did was find a syllabus for one of my first year courses and then obtained the text book by searching online (this site is pretty good http://libgen.rs/) or checking the library. Don't worry about getting the exact version the point is to get a leg up on the concepts.
If you're looking for books, then it depends on what field you want to study. Generally just I'd search for recommended textbooks for that field and then I'd definitely buy it and wouldn't just download it from libgen.is
3Blue1Brown on youtube has amazingly good visual explanations for various math concepts. Helped me out a lot when I was having trouble with calculus. It doesn't help specifically with memorizing theorems or anything, but provides a good conceptual framework to start with. https://www.youtube.com/c/3blue1brown
