Culled from the web, and in keeping with my responsibility to keep the world informed and educationed (ok, it's merely a goal, not a responsibility), here is a whole page devoted to free online education which might prove valuable to many.
Here's are the topics:
Berkeley Courses With Video Lectures
Sites Offering Free Courses
Free Online Documentaries
Learn Languages on iTunes
Education With Podcasting
Useful Free Software For Students
Web 2.0 For Students
Tiny Flash Freeware
Free Ear Training Software
Not kidding. This is a valuable resource. Use it.
