hi,

see the cutoff score changes every year and it depends on certain factors like number of participants in the exam, students category, questions difficulty level, seat matrix , choice of stream etc. every nits has 85% seats reserve for domicile candidates. now the percentile can not remain same for the years, it changes time to time. however securing 95+ percentile is great to take admission in top nits.
