Good places to start for Calculus? I am a student, and due to my school's decision to not teach Calculus in high school (They said we'd learn it in college, but that's a year and a half away for me), I have to learn it myself. I am trying to get a summer internship as a Bioinformatics intern, and I would like to have prior knowledge (I was told I'd need an understanding of calculus to get the internship.)
I have heard of MIT's OpenCourseWare, which I had taken a look at, but I was wondering if there were any other resources (Preferably free of charge, I don't have much money to spend) 
Is there any good online (Preferably free) way to learn Calculus?

Coursera comes with problem sets, the lectures are paced, and you can discuss things with your classmates on the associated forums.
