From a person with only pre-high school math knowledge, what books/pdfs/moocs would you guys recommend in order to prepare for a future computer science degree?

From a person with only pre-high school math knowledge, what books/pdfs/moocs would you guys recommend in order to prepare for a future computer science degree? I've read that I would need linear algebra, discrete mathematics and calculus. Is that right? Is there any resource that targets compsci subjects?
