What do other IITs think of IIT Patna?

Your question is highly illogical and those who invest their energy in getting validation from others never become successful. Who cares if someone says IIT Patna is not good if you are getting excellent opportunities here? Moreover, those questioning the credibility of IIT Patna are the same who are afraid of taking risks and want to stay on the safe side. How will you achieve success if you don’t come out of your comfort zone? 

The Indian mindset forces students to focus on placements more than anything thus restricting their perspective. I had a few friends who did their internships at foreign universities and they told me that their peers always discussed new ideas and concepts and placements were their last concern. 

So, stop thinking about what others think of your college and make the most out of the opportunities available to you!
