Rock Paper Scissors: What is a really good website or software package for learning Algebra through Calculus type stuff?
I am a college student taking Pre-Calculus and want to brush up (try and perfect) my algebra skills. I also want to have something that is more interactive to study pre-cal and calculus with.

I am a Pre-Engineering student, freshman.

I don’t mind repeated activities, especially if I am able to try out multiple stuff and see where I was wrong.

Basically anything that offers practice, especially if it includes interactive instruction to complement my college classes.

Thanks in advance.

When you come to a certain topic, you can also Wikipedia for specific subjects. And don’t rule out textbooks, particularly Math Handbooks that itemize all the rules for mathematics.
