How is the MBA course in NSIBM Jamshedpur affiliated to Kolhan University?

Why are you thinking about NSIBM in the first place? Try for competitive exams and try to get into a top-tier management school.

As far as NSIBM is concerned I would not suggest it. The curriculum is not up to the mark and you need a good education to better prepare you for the future. 

The following can be the reasons if you are joining this college:

• You have scored low in UG.
• You won't be able to clear competitive exams with a good percentile.
• You are a resident of Jamshedpur and it will provide you with a location advantage.

If you are pursuing MBA then join a good college.
