As IIM Nagpur is a new IIM hence it won't give that much weighatge to GD/PI for the final selection as compare to their Counterpart IIM's such as A, B or C.

A,B and C gives a weighatge of 55 to 65 percent to GD and PI. But if you consider last 2 year trend for IIM Nagpur then it gives GD and PI a weightage of 25 to 30 percent only.

That means chances are pretty high as per the CAT marks.
