Universities are now offering more and more online classes for free, some with tests and grades at the end. These courses are not the typical camera-in-the-back-terrible-sound-quality videos proffessors have been putting up. Using the latest technologies they are now designed for this specific reason. The only downside is that it doesn't count as credit towards a degree. Still people who want to keep up with the latest classes without paying for them, those who value learning, etc now have a way to go to them. The subjects range from A-Z. The schools go from Yale, MIT, Stanford, etc.
I think this is a real boon to society, and the world at large. This is one of the great miracles of technology, and I can't wait for what the future has to hold.
Here are just a list of some of the courses available online.
