I am writing a lot about my IIT experience from the viewpoint of a 16 year old. Very few enter IIT when they are 16. 16 + 2 years at Kota = 18 years seem to be the minimum standard. B.Sc. means 19 years, after IAS, PhD just add years. And so on. Nowadays, the average age of freshman at IIT will be 20, and some extending to 30 or more. Alvin Leung, my boss at Apollo in San Francisco, went to see 3 Idiots movie. liked it, but remarked Aamir Khan was so old, he didn’t look like a college student. I refrained. Don’t let his see the real IIT. He would have fainted.
