> they even used to have remedial classes for students who came in through the reservation... it is not uncommon for the general category students to crumble under pressure as well.
So it sounds like IIT is generally a tough place to study at, regardless of how you get in. Surely you would agree that how someone got in isn't really relevant after they've been working for 2 decades?
> in a class of mostly 4.0 students you admit a few 2.0 students with affirmative action, it is not difficult to see how they would have trouble in class. If they also get demotivated and end up not getting much from that education, some of them may not do so well in work life either.
Again, you're making a lot of assumptions. I can argue the other way too - people for whom studies go easy don't learn to work hard. Because of their high GPA and belief in their own intelligence, they may act in an arrogant, entitled, prima-donna-ish way and may not do so well in work life where they have to deal with others. (I don't believe this, I'm just pointing out the problem with making assumptions like you're doing).
You don't know why those "2.0 students" struggled. Maybe it was the first time they studied at an institution with such high standards. Maybe they felt an undercurrent of hostility from their classmates who thought they're not worthy of being there and that affected them mentally.
Look at the present state of things. Don't try to extrapolate from incomplete evidence from a long time ago.
