Okay, except maybe for an Internet connection and electricity bills. But putting these aside, YOU CAN.
Coursera is one good example. It’s an online website where you can choose any of the more than a hundred courses on the list. Mind you, though, these are not the run-of-the-mill types or random subjects. These are all designed, controlled, and kept track by some of the biggest universities in the world, such as Princeton and Stanford.
Moreover, some of these courses come with certificates of completion or distinction, which can be great additions to your CVs. Of course, Coursera gives you an opportunity to learn something without spending a dime at all. You simply have to register on the course you want, work on any activity as much as possible, and read the reference materials. Gather all your powers so you can truly complete the course.
A couple of days ago, I just enrolled in Networks Friends Money and Bytes, which is a Princeton course. I planned to have one more, but I don’t think I would have the time. I think you can still sign up. If you’re interested, please do, so we can probably share notes or talk about the modules.
