Everyone in the construction industry is familiar with NICMAR, but GICMAR is less known. GICMAR, on the other hand, is AICTE-approved. (Diploma of Post-Graduation), Whereas, NICMAR (CISR accredited) offers postgraduate programs in a variety of disciplines.
NICMAR charges a lot for a management degree. The total course fee is around 12 LPA. It is really expensive. If you can afford it, then it is no problem.
For East or west industrial exposure, NICMAR is the best. In the recent placement drive, the average CTC offered at the institute was 6 LPA.
I will suggest you do your own research and choose an institute that is best suited for you.
