Which course should I pursue: MBA in event management or Diploma in event management?

Dear Nisha, Value of diploma in event is not so high. So, you should do MBA in even management. It will help you a lot in choosing a good career. Moreover, after that, you will also be post-graduate student.

It all depends on which college / institute you do it from, and even more importantly what is your own aptitude in terms of exposure, knowledge of the field, communication and presentation skills, operations know-how and street-smartness. You can go ahead and speak to alumni of some event management
