You can find MIT's course materials on the Web. I have found the material to be very helpful. I am taking an online physics course through the Community College of Denver and I'm supplementing what I'm learning by going to the MIT OpenCourseWare site to watch a video lecture series on physics. Here is the link to MIT's course materials: http://ocw.mit.edu/OcwWeb/index.htm
Thanks for the post - I just saw this on CNN.com http://www.cnn.com/2007/LIVING/wayoflife/07/02/things.for.free/index.html
Good info. The OpenCourseWare Consortium has a listing of universities that publish course materials online. http://ocwconsortium.org/use/index.html
