PUMBA and Indira Institute of Management both offer post-graduation courses. The number of courses offered by PUMBA is more than the latter.
Indira Institute of Management offers a PGDM course in two specializations: Marketing and Finance.
PUMBA offers a few more courses other than those offered by the Indira Institute of Management. The other courses it offers are Ph.D., Executive MBA, and MBA in Pharma Biotech.
Thus, one can make assumptions based on these statistics.
