What is the difference between MBA and PGDM Courses

One key distinction is that MBA (Master of Business Administration) is a degree programme that can only be offered by colleges affiliated to universities, whereas PGDM (Post Graduate Diploma in Management) is a diploma programme offered by autonomous institutional bodies.
MBA programmes, on the whole, follow a set curriculum and are more theoretical in character. The updating of curriculum to keep up with changes in the industry and economic landscape has a certain rigidity to it. PGDM curriculum, on the other hand, can be amended or modified at the business school's in order to keep it up to date with current industry requirements and standards. This allows schools to maintain a competitive advantage, and competition stimulates curriculum and pedagogy innovation. In contrast to pure theoretical learning, such systems allow for more practical application-based learning.
