Hi Shashank,
After IIT's, NIT's are one of the most prestigious institutes in India.

Keval JEE Mains

yes but 12 marks is also necessary

Hi there I went through the details provided by you and it isn't sufficient to provide a clear answer. Admission to NIT occur based on AIR issued by JEE(Main). It is calculated based on your JEE(Main) score and board percentage. You will get home state advantage in NIT depending on the state you wrote your 12th exam. Your board percentage should help you. If you belong to nay category, it will also help you.
I would suggest you to go through the opening and closing ranks of the previous year counselling to different NITs. It'll help you get a clearer picture.
All the best!

both are in consideration both are equally important.
