Learn math online!

I am currently taking a College Math 2 class, which I must say is.....painful.  Anyway, I wish I had found this website about 7 weeks ago, I might be better off.  Khan Academy is a site that has countless mathematical equations that are explained and illustrated in clear detail on a virtual blackboard.  In addition, to the video lessons on math, science and a number of other subjects, there are also practice exercises to help you put your new knowledge to use.
