One of my cousins was in NIT, Calicut and he had amazing DASA friends and none of them are overrated. If anyone feels that way it may be because of the fancy English and accents.A few students do get in the limelight though. The most obvious of reasons is their communication abilities in the 'English', which most of the other fellow mates find amusing.
It is okay if we don’t focus on these gibberish facts and we progress ahead from these superficialities and value people for their talent instead.
As, the international reputation of colleges depends on the number of international students. So, DASA students help in increasing the ranking of colleges.
So, on the other hand, look for people, who really do significant work. But deep down the feeling you have in your own inability to gauge the fact that you are lending them this so-called aura and thinking of yourself to be less capable. You may think this is what it takes but think again. This overrated affair is quite hollow, I guess.
