Both IIM Calcutta and IIM Kozhikode are top-notch management institutes in India. The majority of people claim that IIMC is better than IIMK just because it has a strong alumni connection and extremely experienced faculty.
But don’t make your decision solely based on this. Keep your aim in mind before deciding.

You want your personality to be developed to the maximum extent
You have a knack for Maths and Analytical Skills Development
Choose IIM Kozhikode if-
You want to be in the top 1% of the class
You prefer an institute with less dynamism
If you are average at Maths and Analytical Skills Development
The final decision is yours to make.
