Hello Mithilesh,

According to your rank, your expected rank will be approximately between 3,645 - 3,945.

I can help you better if you specify your category and your home state as cut off vary category wise and also cutoff is different for candidates belonging to home state and for other state candidates.

You can also refer to the previous year cutoff for NITs, to have an idea about the expected cutoff for this year and your probable chances for admission. Refer to the link below for previous year cutoff for NITs-
