I would highly recommend ASU's College Algebra and Problem Solving [1]. They have a large comprehensive test at the beginning that determines your knowledge. Should you be missing knowledge, they'll use the same platform to teach you all the prerequisites (i.e. they won't let you take the course until you go through ALEKS, their learning platform). After that's done, this course is something like preparation for college math classes. So far, I like it a lot, thanks to ALEKS. Give it a shot; it's free.
