Hello aspirant,

It is difficult to predict because cut-offs changes from year to year and they vary from NIT to NIT and branch to branch. Also Caste Category of the candidates matters.

You need to get a safe score of score of 180 to 230+ to get seat in good NITs based on previous year's cut-offs.

But cut-offs varies from year to year and depends on many factors like number of seats available, number of students appeared in the exam, caste category, difficulty level of the exam, etc.

You can predict Colleges you can get for your JEE Mains rank using below mentioned link.
