Hi Tejashree, generally the cutoff for every year is based on the number of test takers, difficulty levels of the exams, number of seats available etc. Going by the past records, this score is a very good score for securing a seat in all NITs. This generally generally yields around 500+ out of 1000 basically. It also depends on which category you belong to.

The closing marks for 2018 for some of the subjects for general category are, 

1) Communication systems - 471 

2) Embedded System - 461 

There are various other courses available for different cutoffs, wherein please refer to our website for more detailed information,
