I need to catch up on my math skills before college. I never even got to take Algebra II or Geometry in high school. I’m going to study Computer Science, which is very advanced math heavy, and I’m worried I won’t be able to keep up because I haven’t taken these high school courses.

So can anyone point me to some online video tutorials that can teach me some things I need to know? Anything along the lines of advanced algebra, basic calculus, or geometry.
