One of my friends studied at Guru Nanak Dev University (GNDU) Amritsar. According to him, the environment is really good, green and clean.
Other departments like Chemistry, Law, Political Science, Food and Technology, Architecture are really good. There is no union of students like a political body makes it a bit better. Very few cultural programs take place here. The library is the most peaceful part of the campus and is accessible to all the students anytime.
