MOOCs you've done or started, and your opinion of them

[bluebooger]

I did a bunch at coursera back when everything there was free -- python programming from Rice University (great set of courses), Statistics from Duke University (great course) , couple of R courses from johns hopkins (ok courses), C++ for programmers (awful course), C# game development (awful course)

I don't think I'd pay for anything at coursera (even though they're only $49 a month now)

I've done a bunch at edx for free -- CS50 might be the best mooc ever if you're really interested in learning computer science in detail , also did a 3D programming course (awful)

did a unity and a gamemaker course through udemy -- both were great -- got them on sale for $12
