Hello!!!

Hope you are doing great!!!

The required percentile to get seat in NIT's is around 96 percentile in JEE Mains.As per the previous year scenario,to get Seat in Top NIT's, the average cutoff lies around less than 30000 to 35000 All India rank which comes nearly 170-180+ marks in JEE Mains to get seat in top NIT's in Mechanical Engineering.But the cutoff's may change year to year.You can go through the link to know about the cutoff's in Top NIT's : https://engineering.careers360.com/articles/jee-main-cutoff-for-top-nits
