Can get admission in nit from cbse 74.6% and crl rank 302000 and obc rank 106000 through csab

Hello,
I am sorry to inform you that with XII percentage of 74.6%. You become ineligible for admission through JEE Mains just by a whisker. That's includes both JoSAA and CSAB. NTA requires you to be either above 75% or in top 20 percentile of your conducting board. For CBSE top 20 percentile is well in around 80 and above percentage.
You are ineligible for Admission in colleges through these two counselling ofcourse considering you don't belong to SC/ST. Otherwise, there is a relaxation in minimum percentage required.
Thanks
