dear student

it depends on the rank mostly rather than the marks. and also it matters what category you are.

the TOP NITs are trichy, surathkal, calicut and warangal and the rest of them follows. for getting into top 4 NITs i am giving the range of marks and ranks for different categories. remember they vary from year to year.

General- marks range(750–650) Rank(1000–2500)

OBC -marks range(700–580) Rank(2000–8000)

SC/ST- marks range( 600–400) Rank(5000–20000)

hope this helps

All the best!!!
