Hi

Admission in IITs is through jee advanced and not jee main

This difficult to predict the marks/percentile / rank you require in JEE mains to get into NITs etc as closing rank keeps changing every year  depending upon various factors like

----------) number of students/ candidates  that appeared in the  jee main exam,

-----------) number of available seats,

-----------) jee main examination difficulty level.

-----------) branch preference by different candidates

-----------) the category you belong etc.

But yes,

When we go through previous year trend then ,

Under other state quota , closing rank for some of the nits for which closing rank goes low are listed below along with their closing rank in the 6th round of josaa counselling 2021 for obc category  :-

------------------) National Institute of Technology, Manipur:-civil engineering :-  16470 obc rank

------------------) National Institute of Technology, Mizoram :- civil engineering :-  16651 obc

------------------) NIT, Raipur :- Bio Medical Engineering :- 17047 obc  rank

------------------) National Institute of Technology Agartala :- chemistry (5 Years, Bachelor of Science and Master of Science (Dual Degree)):- 17842 obc rank

So, to get a seat in NITs, you need at least around 16k - 17k obc rank, and for that you need at least around 93+ percentile  as per past year trends

So, with 80 percentile, chances for NITs is extremely low.
