I always lurk in this board and I feel like a brainlet.

I'm 18 and my 2 parents forced me to do social studies (they are both lawyers and they want me to be one). I feel like being a lawyer is blue-pilled.

Anyway, I have nice grades and I will be able to apply to statistics.
But I want to start learning both math and science.
The problem is I don't know shit about anything related to those.

What's the first thing I should do?
