Rubbish, rubbish.
If a guy failed in a course 3 times, he would have gone through the gamut of professors who teach those courses.
Furthermore, this is India, where affirmative qaction has run amuch, and there are fixed Quotas for so called "Lower caste" students to be admitted to institutes like the IIT, where everyone else enters strictly on merit (admission rate of less than 0.1%!
If youre competing with the best minds in the country, and you yourself have come in on this "quota" or that "quota", well, you got in, thanks to government legislation, and not because you had what it takes.
But you cant pass your courses on quotas too, now can you??
Apparently you can in the US.
