Open Courseware

Education is practically free these days.  Just do a search on "open courseware", add a topic like "computer programming" or  " mathematics"  and start poking around to see what will work for you.  Here are some resources we've found.  We haven't delved into all of them, but I can recommend the Khan Acadamy, Art of Problem Solving videos, and MIT from personal experience.
