Hello,

You get 80 percentile then your rank will be above 1 lakh. And NITs means National Institute of Technology college get rank between 30000. So it's quite difficult to get NITs in your rank. Infact if you are a general category student then minimum marks is 95 percentile for getting NITs. So if you give the next attempt of JEE Mains examination then be prepare for getting 95 percentile marks.

All the best.
