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.
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
