As some of you know, I'm a teacher by trade, so when I saw this I thought it might be something useful for some of you.
MIT has an online offering of several of their courses available free for download. You can't get your degree from them online, but the ability to download material useful to your studies free of charge from a prestigious institution like this is absolutely priceless if it relates to your degree. The cost of one textbook should be enough to make you want to take a look at this.
"MIT's online offerings, published under an open licence that encourages reuse, redistribution and modification for noncommercial purposes, include lecture notes, exams and lecture videos from more than 1,800 courses, virtually all of its curriculum."
