Recommend any site where I can learn online for free?

Do you guys know any site where I could learn anything online for free,? If you have any idea, please recommend it to me? I'd appreciate it a lot, PARTICULARY SOCIAL SCIENCES? Some that are really hard to find in Google.

https://www.coursera.org/category/humanities [I have tried some of these, they vary but are great introductions to topics. Interactive.]

http://ocw.mit.edu/index.htm [I have not tried any of these.]

http://www.openculture.com/freeonlinecourses [Non-interactive courses. I have listened to a few.]

Khan academy is good for just about everything. As far as social sciences, there are huge sections for econ and humanities.

Stanford also has some open course classes if you care to sift through it to find them or have a specific topic in mind to search for
