Hello dear student,

I am hoping you are aware that every year cut of changes and there is no fixed cut off marks or percentile as such .  While according to the 2019 qualifying percentile for SC category student  was 54.0128155 .  You can really not predict this but all j can suggest you is to do only those questions on which you have confidence in and try to get as much as marks you can score. Other than this try to get marks above 140+ so that your chances to get into nit increases . I hope this was helpful

Thank you
