Scott H Young has recently completed an interesting learning experiment where he took online MIT classes towards a computer science degree. For just $2,000 he received the education from MIT using online resources in one year!
Watch his TEDx talk part-way through the MIT experiment. Since the talk he has finished his goal of completing the MIT degree program in 1 year.
While he missed out on the traditional college experience of networking, he saved hundreds of thousands of dollars to teach himself. He called it the education "a la carte."
