Why does Kalasalingam University have a good NIRF ranking but bad student reviews?

The reviews of the students are not usually bad. But when you compare Kalasalingam University to other more established universities, it lags a bit behind in the college rankings. But the college rankings are not given by students, so their views vary.

This college really has good facilities, a huge library, green campus, etc. They also have a well experienced and highly cooperative faculty.  The college might have some faults which is why the NIRF ranking is not good. But other than that it is quite a good college with sufficient amenities.
