I am from India, and I have experienced the kind of pressure that this article is talking about. Personally, I feel that the root cause of this kind of pressure placed on teenagers is the abject fear of failure that is prevalent in India, especially in the middle class population. If one cannot crack these exams with flying colors, then society(most part of it at least) writes them off as losers who are doomed to a low paying job with no prospects of success in life, financial and personal.

A lot of people equate academic brilliance with intelligence and build up on that logic that it'll lead to financial prosperity, which in turn will lead to a good image in society and hence happiness. Don't have good marks, you are worthless. Never bother if you are a great athlete, singer, artist or any of the other vocations.

Even within academics, if you can't make it into one of the areas which pay a lot, like CS/EE/Medical science etc, then society views you with pity about your wasted talent. Doesn't matter how skilled of a Civil/Mechanical engineer or architect you are.

I feel lucky to have been exposed to the western system to get out of such a though process and hope that India can pick up some good things from the west in the field of education.
