Dear Student,

There is not a certain score so that you can clarify the cutoff with the help of marks but you can predict it through the rank. So you need to check the rank in your scorecard.

For a home state student, if you come under the rank of 100 then there is a good chance that you can get CSE here after 2 or 3 round. And for open state if goes under 50.

for more details you can check this link.

Good  luck :)
