When a guy who gets 1000+ in the board exams out of 1200 fails miserably in his degree, what are you supposed to think ? That the teacher failed him in teaching the way he would be interested in learning, that he has lost interest in studying, that he finds playing more fun, that he has decided to fail, that he doesn't care.... What are you supposed to think ?
I fail to understand this and it hurts for either the person has lost interest or he has been put into a situation (by himself or others) into such a situation.
Retrieving oneself and going back is an arduous task. It can be done, if everyone walks their bit, but then who is ready to do that. The easy way is to point a finger and give up.
