Colleges in Kolkata

I agree with Ritesh and also advice for UEM Kolkata to pursue hospitality management for good career prospects.

First of all, BIT-Kolkata extension centre doesn't offer M.Tech and for getting admission in the main campus in M.Tech, you will need a valid GATE score.

You can refer the website link of IEM Kolkata to get required information for admission to MBA programs in good college of West Bengal https://www.shiksha.com/mba/course/master-of-business-administration-mba-iem-institute-of-engineering-and-management-salt-lake-city-kolkata-89283.

The best colleges that are offering MBA course in Kolkata are:
IIM (Indian Institute of Management)
IIFT (Indian Institute of Foreign Trade)
IEM (Institute of Engineering and Management)
Praxis Business School. Calcutta Business School. University of Kalyani. Calcutta University.

Both colleges are very good at their own merits, but according to me, you should go for Loyola College because this college is older than St Xavier and with better education and placement facilities.
