Hello applicant,

To secure  seat in IIT, you should mwet the eligibility criteria of  SC category cut off of JEE main and then Jee advanced.

By previous year cutoffs the cut off for jee main for SC category was 54.012 percentile.But as we know cut off changes every year. It depends upon the  number of candidates appeared and qualified in exam, difficulty level of exam, previous year's cut off etc.

So you should score minimum 56 percentile to be on safe side.
