Dear student

NMIMS is a management school. Do you mean DJ Sanghvi COE or Mukesh Patel STME? These are two neighbouring engineering colleges that come under the same banner as NMIMS. 

DJSCOE would cost around 1.2 lakh a year for college fees. It goes +/- a couple thousand. MPSTME on the other hand is roughly double that. I won't go into pros and cons of both the colleges. Living costs can vary a lot depending on your preference but you can take an average of about 1 lakh/year for a shared room (a friend of mine pays that much). 

These are of course rough numbers. The exact number depends on your choice of college, stream etc.

Hope this helps

All the Best !!!
