Hi,

See, as per your query there is a reservation policy which is followed by all the IIMs, it goes as:

15% seats at the IIMs are reserved for Scheduled Caste (SC), 7.5% seats are reserved for Scheduled Tribe (ST), and 27% seats are reserved for Other Backward classes and 3% for PWD

This criteria is followed in all the IIMs.

And regarding the graduation percentage, to qualify the criteria you need a minimum of 50% to satisfy the criteria for any IIMs.

Hope this helps.
