Hello Aspirant,
As we go through the latest cut-off of 2020 then it shows that the closing SC rank was 9986 for Smart Manufacturing branch in IIIT Kancheepuram for SC category.
And this year we saw a little dip in the cut-offs so it is possible that this time we can see some increased closing ranks but at this time it is not possible to say it exactly because it depends upon many factors and those factor keeps changing therefore the cut-off varies.
