Event Management in Kolkata

You can't just describe a college to be best upon the placements (reason I will explain below). Also the course structure of event institute are also something they are experimenting with the students at this moment. So I will try to be very specific upon the topic about best institute. There are a number of institutions available with different courses in the market. The institute are like:
NAEMD
NIEM
EMDI
AMITY UNIVERSITY, etc. Courses offered by them are like:
Post-Graduation or MBA in Event Management - 2 year course
Graduation or BBA in Event Management - 3 years
Post graduate Diploma in event management - 1 year
Diploma in event management - 1 year
Certificate in event management - 6 months etc. Courses I am not sure about. In all the institute and in all the courses offered by them, they send student for exposure in events. The reason to do so is to get them ready for jobs and the industry as well. Now the chances of the student ending up with placement totally depends upon how much have you learnt in those events. And also upon the below mentioned points:
How spontaneous are you?How are you different from your college mates?How more are you willing to learn and understand in coming time period?
How good are your skills in communication, negotiation, persuasion etc.?
