Does that even matter? You see if we keep on pondering upon what others might think about us, we’ll never get the chance to be ourselves.
We can never keep everyone happy, trying to do so would mean killing your own life.
So don’t think about what other people or other IITs think of your college(because most of them don’t think good), every IIT has been established because of a reason , it is sad that many people don’t consider new IITs good, this just displays the Indian mentality of going by the best route rather than stopping and exploring things. Life of an average Indian student irrespective of his/her college goes into thinking about Placements, Salaries and all.
Some of my friends who did a foreign internship this year told me that there students discuss about new things or the topic taught in the class. He hardly noticed anyone talking about placements and salaries.
So if you have taken admission into IIT Patna, sit tight, try and learn as much as you can, experiment with things, build a better relation with your professors. Then you’ll definitely beat the best guys of all the old IITs.
