dear candidate if you are belonging to general category there may be less chances for you to get a seat.

but incase if you are not a EBC then you gave good chances to get a seat in nit but you cannot make it into top  most NITs

Dear candidate

As you did not mention your category in your query and getting seat at NIT depends on your rank which depends on your category so, considering general category in general it is impossible to get seat in NIT with just 80 marks in JEE MAINS as you barely qualified and if you want to know eligible for any other category mention it so that I can provide you with the required information.

Hope this Information is helpful

With 80 marks, your rank will be roughly close to around 1,74,900 and percentile will be approximately 90-91%. Check out the site below for some details regarding the same...

But with this marks, you cannot get into NIT for sjure because NIT admission ends around 96 percentile and above roughly around 33-36 thousand ranks.

So you need to score approximately 170 and above to be on the safer side.
