What do I need to study before precalculus?

Summary: I need to know what to study in order to prepare for precalculus

I'll be starting classes in spring and I'm working towards a bachelors in computer science. My first math class will be precalculus. Math has always been an intimidating subject for me(my WEAKEST subject), but I'm willing to work as hard as possible to understand it. I wanted to know what I should be doing now in other to be ready (like a Khan academy course?). I'm willing to set aside 4 hours a day for studying. Thanks for the help.

Why not look at textbooks in your school library, pick one you like, work on your own and drop by this site with any questions? I don't know if there are classes to prep for precalc , as it is a basic course in most schools.

You can find appropriate books here, e.g. https://openstax.org/details/books/precalculus
You will sooner or later meet discrete mathematics on your way to computer science. This is more or less independent from mathematics at school so you could read about it independently.

Algebra...
Khan Academy would be a good place to start, or if you want a textbook, a search on Amazon or other booksellers' sites would turn up lots of textbooks.
