I have recently graduated from high school, and intend on continuing mathematics study in university. For the next couple of months, I don't really have anything to do, and would like to continue doing math in my spare time.
The math I've done so far (and enjoyed) is calculus and optimisation, linear algebra, vectors, vector calculus, complex numbers, and matrices.
I guess my question is, how do I do this? I've had an idea of working through problems from my high school text book, or even borrowing a university level textbook. Are either of these good ideas?
How do you study math in your spare time?
