Difference makes the DIFFERENCE
for the people, who cannot join any IIT, inspite of all their hard efforts, and people like me, who are not eligible to join any IIT, still, to be taught by professors of IIT - Madras.. is a great previlege
One should join the course to understand and appreciate the course, untill then, what ever I write here will be unworthy... !!
I could do this course at my convenience and at my confort, watching all videos, till I get to the point of satisfaction to understand the presented concepts.
