I’ve recently gotten addicted to “attending” college courses via iTunes U. With iTunes U you can watch or listen to lectures from various colleges around the world, and some courses are even supplemented with assignments and notes. My favorite so far is Harvard’s CS50 (video from YouTube below. This isn’t the same lecture as the one on iTunes U). The professor is a great speaker and is quite entertaining.

iTunes U is useful in many ways. You can use it simply to sate your own curiosity, or maybe you want to preview a subject before taking an actual course on the subject. It also may be useful to watch a lecture or two on a subject you’re struggling in to see if a different approach will help you understand it better.

The best part about iTunes U is that it’s free (both the app and lectures featured in the app). So get out there and learn something!
