Hello Rohit,

You can take admissions at NITs through JEE paper 2 via 2 quotas, i.e.

1. Home state quota

2. Other state quota

The cutoffs are also different based on category (Open, OBC-NCL, SC, ST)

You can visit the below link to know the trends of opening and closing rank NITs based on quotas & category
