This is a collection of free online college courses from the Indian Institute of Technology — Delhi.

There are a wide range science and technology courses represented here: Electronics, Mechanics, Information Systems, as well as several Mathematics courses.
There is a mixed-bag of resources available here: many of the Basic Courses have a full curriculum of lecture videos, while some of the more advanced courses currently offer only on-line syllabi.
Another nice resource for students and teachers!
