I have become a big fan of free education to supplement my not-as-free education. I really enjoy taking classes through Coursera and EdX (prefer Coursera), and love the ability to take a class through some top-notch schools and programs without having the burden of tuition!
Free, online classes such as : Computer Architecture, Control of Mobile Robots, Computer Vision, Introduction to Computer Networks, Introduction to Sustainability, Nanotechnology, Startup Engineering, Learn to Program, Introduction to Digital Sound Design, Surviving Disruptive Technologies, Creative Programming for Digital Media & Mobile Apps, Human-Computer Interaction.
Yup, I've personally done that. I never pin anything for others but this one I couldn't pass on. It's true, you can take actual classes from Yale or Harvard or university of Edinburg without leaving your couch. Make something of yourselves, people!
