What should I choose - Maths and Computing in IIT Kharagpur or CSE in IIIT Hyderabad?

A simple answer to this question would be IIT Hyderabad if you are looking for better academics and job prospects and IIT Kharagpur if you are on the lookout for a good social life.

Honestly, the course of math and computing at IIT KGP lacks the necessary requirements to impart true knowledge related to math and computing. The only reason why people still go for this course is the high placement packages offered at the end of five years.
