I don't think it is any different from teaching at any other place. The basic principles are the same as I covered in my previous answer: Brijesh Kumar's answer to How do top teachers teach?
I don't care that I am teaching in IIT when I am in the classroom teaching. I don't care that they cleared JEE. I don't care that they are the "best brains" in the world. I care that I should give them the best possible knowledge in the best possible manner. That is all I care about.
I like to blog about various topics ranging from education in IITs to social issues in India and US. All opinions and views presented here are my own and not of my employer.
