Have you guys heard about
Coursera?
It's a website where you can enroll in some courses held by different colleges around the world. They are totally free, or so it seems.
But there are a lot of interesting things there, and you even get a certificate for attending them( but I think it is this certificate that isn't free).
- What is the actual method of "attending" these courses? I couldn't find out, is it participating in some kind of conference like you'd do with google+?
- Is it compulsory to attend all the hours? If so, this is hard to manage for people with a busy schedule.
- Finally, what do you think about all this?
