So like. I haven't done math in a long time.
I want to learn some hard math.
Is there a website that will teach me hard math and then I can do tests for free? Thanks math men.
Ps I know a guy that has a degree in math. But he's a friends brother and moved.

Try edx or coursera or something like that. Type "free online classes" into a search engine.
