Several months back, we mentioned how the Indian Institutes of Technology (otherwise called the IITs) had launched a series of free technology courses on YouTube. You can find about 50 free courses here in total.
As a quick follow up, it's also worth letting you know about a new series of courses being webcast live (and in English) from IIT Bombay (watch here). According to the head of their Centre for Distance Engineering Education Programme, you can watch the live transmission of 35 courses. A schedule of fall courses can be found here. Please note that the times referenced here are in Indian Standard Time, but you can use this time zone converter to make sure that you're in sync.
For more free online courses, see our own meta list of Free Online Courses from Great Universities.
