Hello student,

For a ST category student to get into an IIT he/she should score atleast 5% in each subject(PCM) and an aggregate of 17.5% marks in total. Remember that the cutoff marks and percentage are not the same every year. The marks and the percentile change every year according to the highest marks, number of students appearing.

If you want to know the marks cutoff or the percentile cutoff of the IIT's with the branch you can go through this link for more information.
