Greetings!

The cutoff ranks for the year 2020 have not been declared by the authorities yet. They will be declared after the conclusion of the counselling sessions. Since you've not mentioned your aspired branch, I would suggest you to visit the links below, to get an idea about the ranks and previous year's cutoff for NITs and IIITs.
