Maybe I am behind the times here as MIT released this in 1999, but it is awesome.
One of the worlds greatest universities releasing their educational content for anyone in the world to view, study, and better themselves free of charge.
the site is: http://ocw.mit.edu
they have a lot of content; video lectures, problem sets, lecture notes, and more. Topics from many departments; Mathematics, History and many more.
I can not speak for other content areas, but obviously MIT is known for mathematics and technical education throughout the world. I have been studying the Differential Equations Course 18.03
and there are many other courses I intend to take a look at.
I have tackled the first of 32 lectures of the 18.03 and am working on the first problem set that corresponds to the lecture. In other words do more than watch, do the homework and actually learn stuff. I look forward to completing this course and "taking" more courses.
MIT is clear about the mission; this is NOT an MIT education, but it will give you insight to their educational process, the world, and make you a better person. Just like reading a book will. You get bragging rights and understanding if you take it seriously.
I will probably also study some Engineering and Linear Algebra courses. I think you should take some too.
