edX is a website where you can take college/university level courses from colleges and universities, like MIT, Harvard, Berkeley, etc.
I will be taking 8.01x, Classical Mechanics, from MIT (Massachusetts Institute of Technology), starting on Monday.
If anybody else is planning to take this, or is now planning to take this, PM me if you want to possibly collaborate on assignments/projects.
It doesn't count as an actual MIT credit, but employers/universities will most likely count it as one. Also, you get to learn-- from MIT.
(edX is where I learned Python- and got a B in the MIT course)
Coursera is nice as well, same idea.
It has a very nice course on algorithms (well, nice for someone learning everything on their own).
