Could you please explain about the kind of ROI. I couldn't find the name NIA in many of the covered MBA institute rankings.

It is so because, NIA hasn't marketed itself anywhere. The ROI differs from person to person. In general, the fees is 9.68lakhs for 2 years with average placements of 6.87lakhs. Out of top 5 offers, 3 offers were made to freshers and 1 offer to a person with 9 months experience.
