If only Indian colleges worked that way. They have only one way to get it (I mean the finest one's IITs/NITs/BITS/IIIT/Best state colleges), give there entrance exam after 12th class. Crack it, your in, don't crack it, your out.
This is pretty much the way it is in any country with a non-dysfunctional school system. Germany, Japan, etc.
In the U.S. we have been hypnotized by the notion of everybody is special" and "anybody can make it". (Also, "everybody has to go to college if they want a good job".) This sort of milquetoast egalitarianism has had the expected result: diminished educational standards, even the Ivies. If you flunk the university admissions exam in Germany, you can still go to trade school and end up with an education at least as good as a U.S. undergraduate degree.
