I got 427000 crl rank in jee mains and I got only 60% in 12th class Can any chance to get in NIT if I clear jee advance or in special roun

Hello aspirant.
The main two criterias for getting nit are:
1.you should be in top 20 percentile of your respective board
OR
2. You should get a minimum aggregate of 75 % if you are from general or obc category and 65% if you are from ST or sc category
If you are from Cbse board you fail to satisfy both these criterias and hence you are not legible for getting seat in nit or iiits or iits.
If you aren't from Cbse then check your state board top 20 percentile.
All  the best.
