Why don't you move abroad?

>Though secretly, it was to give hope to the students who were defeated by the education system and told “You can’t study Computer Science, because you didn’t know Carbon has a radioactive isotope.”

Forgive me if I'm being elitist here, but this seems like a strange example of outrageous admission requirements. I would have thought knowing about radiocarbon dating (which I'm assuming this is a reference to) is common knowledge (I believe it's in the standard curriculum for grades 7-9 in my country), so it doesn't seem like a completely unreasonable test question. If this is an example that the author uses from his or her own experience, it seems stranger still.

>Every evening, my brother and I would sit in front of an oil lamp and study, mostly maths and science.

It reads to me like this was on the exam for getting into the CS program in particular, though. Which makes it sound like IIT has dealt with the very large number of students who want to study CS by trying to limit it to the overall academically strongest students?
