This might very well be the golden age of learning. If you ever wanted to pick up a new skill, learn a new vocation or just pursue a hobby, it is all out there. Most of these sites use videos to teach, contain some basic courseware and a few exercises to test what you've learnt. It isn't expensive either, and in some cases it might even be free. So, which one should you pick? Here's a list to help you break through the clutter.

Udacity is hyper focused on tech topics, ranging from learning to be a Data Analyst to something as simple as drafting the perfect cover letter. While the simpler courses are free on the site, anything offering a micro degree or with some potential to get you a job will cost you. Unlike the courses on EdX and Coursera, most courses on the site are either sponsored by a corporate or feature teachers hired by Udacity itself.
