Compare number of schools affiliated to CICSE to that of CBSE and other state boards. Also compare the number of students they have.ISC board has a lot of practicals. :-/
Most brilliant students aren't lucky and/or rich enough to get good schooling in India and even if they do, they're pushed towards engineering. Couple this with the ridiculous caste based reservation system where even a rich SC/ST candidate with 20% marks gets admission while a General/OBC (stupid creamy layer criteria here) with 80%+ marks doesn't.
People here get a B. Tech first and then decide what they actually want to do.
