I found a place where you can take self-paced courses in almost anything including Computer Science for free or for a small fee get your certification. I am currently studying R from Harvard. You can find the website at www.edx.org/. There are so many areas to study and they offer several languages too. It's really a cool place. I see courses in solar energy, all kinds of computer science, business management, humanities, languages. It's a great way to brush up on your skills or learn a new one. Let me know what you think.
