Hello Ashin Krishna. BBA is a course which can be undertaken by students from every field. It teaches the students, the basics of management ranging from marketing, finance to logistics and supply chain. The eligibility for the BBA course is 10+2 or equivalent from a recognized Institute.

So,  with the diploma degree in mechanical engineering that you have, you can easily enroll for the BBA course.

All the best.
