Dear Ujjwal,

Calcutta University, also known as CU, is a college of very high repute. It was established on 24th January 1857. I have studied some reviews about the college and the results weren't too great. There are many answers on social media where its own students wrote badly about CU. But, we can't judge the college solely by this. You may join this college, but i suggest you search for other colleges too.

Hope my answer helped, don't hesitate to ask further doubts.
