Hi,
IIMC Hyderabad does not offer BCA course.

Either you have no idea what a management education is. I hope you are aware what an IIM is, if not please do search it on google. IIM Kolkata, IIM Ahmedabad, IIM Bangalore, IIM Indore and IIM Kozhikode are top institutes in India.

Executive Programme in Business Management (EPBM) at IIMC is to help you understand the basic concepts of management. It will help you to build and develop general management skills and management functional competencies. As there is no campus placement opportunities for EPBM students, you may not directly get any benefits with respect to increased salaries. If you change your current job, you may get increased salary or promotional avenues after EPBM. It is difficult to predict what increase you will get. It will purely depend on your previous experience and sector in which you want to work.
