MMS Eligibility

I didn't understand what you want to know, your GMAT query and JBIMS have no connection. If you are looking for MMS 19-21 batch with JBIMS, then you need to give CET buddy,

It does not matter you have engineering, B.Sc or B.Com degree, all are eligible to take the exam and prove their potential. If you are capable of getting that one seat than it is definitely good for you to join JBIMS because you have proved your potential to compete by securing that seat. For your knowledge, yes students over here are of great mix, some from B.Sc. B.Com LL.B.Pharma, etc. Believe in your potential and never doubt your degree as ever degree gives you certain skills which upscale you from others.
You need to be hitting top 40th rank in MHT CET for open category.
Hope I helped!

The cut off at SIESCOMS was 95.6 percentile and at PUMBA it was 93.7 percentile.

Hi, No JBIMS accepts only CAP of DTE by Government of Maharashtra, so CAT, MBA CET,CMAT exam scores are accepted not MAT by ATMA. All the best.

MAT score are not acceptable; placements of MMS are almost 100 percent.

For MMS program, you have to go through the CAP process and the process has a major weight to the CET exam. But for PGDM, you have a fair chance of conversion but your selection will depend on your performance in GD PI.
Good Luck.
