Distance MBA

I would suggest you to look for the rate of return (ROI) for every university/institute. It's calculated as ROI = Package expected or avg. package divided by fees of the college. For e.g. - for BVIMR average package is 6 LPA and fees is 6 LPA. So ROI would be 1.For Amity average package is somewhere around 8 LPA and the fees is 12 LPA. So ROI would be 0.67. Choose a college which has the highest ROI. Among the institutes you have named, NMIMS and Symbiosis have very good ratings. The fees in NMIMS is around 19 lakhs for MBA. Choose a college for which you are confident that you can "earn back" its fees in 2-3 years. BVIMR and Amity stands same on ratings, with IPU lower than them.

In my opinion NMIMS MBA Core Mumbai would be a better option than SIBM Pune or SMHRD which are the flagship campuses of Symbiosis. NMIMS has a more stringent admission policy and a more rigorous academic structure. Overall the quality of NM students would be much better than SIBM/SCMHRD
