Can I get a call from XIMB HR with an NMAT score of 189?

Most probably, no. Here are some reasons why you have negligible chances with this score.

• Conservative estimates put XIMB HR in the 205+ score range whereas generous estimates put XIMB HR in the 190+ score range. According to the 2020 trends, the NMAT cutoff for XIMB is 200.
• XIMB is one of the prime management colleges with a great curriculum and great placements, thus leaving no reasons for the cutoff to go below 190.

• 190 is even lower than generous estimates for NMIMS Bangalore and NMIMS Hyderabad, which are not as good as XIMB, as per most national-level rankings.

Although there are little to no chances, you never know what is the trend each year. You may get selected next year or maybe not, it all depends on the number of seats and highest score. The best advice here is to prepare well and give a retake.
