In NMIMS, BBA is not as reputed as the other courses. Many students don’t join the college after the selection so you might get selected in the second or third list. 

One of my friends had the rank of 3000 and he got selected in the first list of the Bangalore campus. With a merit number of 2440, you have around a 50% chance of getting admission to the Mumbai campus.

If not in the first list, there’s a fair chance that you will get through the second or third list. Hope this helps.
