Dear All, We think free education is not possible especially in countries like INDIA. But all top universities in the world including our IIT's are offering free education to everyone through video lectures, audio lectures and animations (interactive). But a few of us know about them. This is an effort to create awareness about the Best free educational resources available in the world. Here are .. 1. Free video lectures and animations on all subjects Huge Collection. Text materials and videos on all Engineering and Medical Sciences. 2. Joint venture by IIT's and IISc 3. MIT Open Course Text materials, video lectures on all subjects 4. MIT world Video lectures 5. MIT lecture Browser browse video lectures on all topics 6. World Lecture Hall you can find any course here, where ever it is. 7. WGBH Forum Network videos on all subjects 8. Vega Science Trust Physics Special 9. Micro Biology Video Library Biology 10. Animations Genetics, Biochemistry, Immunology, Physiology etc... 11. National Institutes of Health Medicine Special Business, Management and Leadership |
1.
2. Interviews with Great Entrepreneurs
3. HARVARD Working Knowledge
4. Stanford University Videos
5. Knowledge @ Wharton Business
6. Huge Collection of many other including the above all.
