I am right now going to try for quarter 7 of the course (starts in November)

There is a math entrance exam that deals mostly with college algebra and calculus. So you will need sufficient math back ground to qualify for the course, but after all the 12 quarters of the course (That's if you get in) You get a certerficate upon completion. Which I thought was VERY cool and this is all completely free so I thought I'd share it with the more intelligent population of Zelaron.
