Cutoff mark cannot be predicted exactly because it depends upon various factors.

You should score more than 220 in JEE Mains paper-2, to get a seat in NIT.

All the very best and good luck.

Dear Sai Manoj,

You should try to score more then 230 marks in JEE Main paper 2 to get admission in NITs.

To be eligible for NITs you should have 75% marks in your boards exam or you should be in top 20 percentile in general category. For SC/ST it is 65% marks.

Good Luck!!
