For IMT Ghaziabad, it requires a 90 percentile in CAT. Apart from that your past academic records and your profile also matters.

For the other 3 campuses of IMT which are Nagpur, Hyderabad and Dubai, you'll get a call if you have 70 percentile. For Hyderabad and Dubai you may get a call at even a 60 percentile.

Moreover the GE/PI rounds of the Ghaziabad campus happens separately while the process is same for the other three campuses.

All the very best
