I am going to study before class starts!

I am posting publicly so that I will feel more obligated. I need a few more advanced math classes before I leave community college and go to university. I have worked at University for 10 years (almost) and see that it might be a rip-off. As I am over 40 years of age, I cannot lay out much money and hope to make it back. Failure is not an option now either. This video id from Khanacadamy.org . Khan is worth a look-see no matter how little time you have, improving the mind is always good!
