I found this excellent post about free online courses before my database crashed and I thought it would be worth resharing. Taken from here
Not headed back to school this fall? You could be, minus the exorbitant tuition and without even leaving your chair. The web has made it easier than ever before to get a free education, and you’d join the ranks of great thinkers in history who were also self-taught, like Joseph Conrad, Albert Einstein, Alexander Graham Bell, Paul Allen, Agatha Christie and Ernest Hemingway. You, too, can be an autodidact; the breadth of free educational materials available online is absolutely astonishing.
Note: Many colleges and universities offer free courses online in the form of podcasts, lectures, tutorials and full-blown online classes. Most of these courses, while extremely smart-making, will NOT award any college credits or degrees.
Grab some larnin’ from the University of Washington’s free online courses; Greek mythology, American Revolution, Heroic Fantasy are just some of the offerings. If you get tired of that, you can study economics at the University of Nebraska.
There is a lot more. So I suggest checking it out.
But if you don’t want to look at each site yourself, I pulled out a few of the best.
