One of the most wonderful impacts of Internet is it makes many knowledge freely available. You can still attend the courses from the best universities in the World, without having to spend a bunch of money to get into US. You can now access the precious contents from the other half of the world. Of course, it’s still far from effective as when you come to classes, having friends and assignments, for real, but it’s undeniably a huge benefit.
The knowledge is yours!
