How is Krupanidhi School of Management-Bangalore to pursue MBA?

Yes, As per AICTE norm without minimum 50% in graduation for open categories and without minimum 45% for OBC.SC and ST, one cannot seek admission to MBA So be careful

There are lot many other colleges which are worth in terms of fees compared to Krupanidhi School of Mgt.

The first thing I would do is to see if the institution is AICTE recognized. They also could have a distance education program. Make sure that you check these details first
