The Best Things in Life are always Free

Well, probably they are always not. But these days, information is. If you truly have the passion and drive to learn something, then the opportunities today are wide ranged thanks to Internet.

MIT Open courseware gives everyone an opportunity to experience the standard of its courses from previous semesters. Some of them might be outdated with respect to changes in technology but many core courses are usually not. Here is a link to MIT Open Courseware

Other universities offering free online courses that I have come across are below:

Carnegie Melon
Stanford
Tufts
UC Berkley
Utah State University OpenCourseWare
Johns Hopkins OCW
Notre Dame
Yale

To find courses available from several countries, use Open course ware consortium

If you are interested in a specific course use OCWFinder to find all the options that you have. Good luck.
