Hello aspirant,

Congratulations for the results. Hope you are doing well. To get admission in NIT one needs to score atleast 75% in 12 th boards and also the score is seen of physics, chemistry and mathematics and not for other subjects so your 86% will not be valid as you have to go with either all the subject or physics, chemistry and mathematics and English and one more optional subject.

Hope this helps

If any queries feel free to ask

All the best!!

Regards
