Hello AK Nirala,
You gave got a percentile of 70.6. and you belong to OBC-NCL. Right? I am afraid that your percentile is lower than the cutoff percentile of 74.31. announced by JoSAA for eligibility of registration on their portal. In view of this you will not be allowed to register and hence can not seek admission in any NIT.
Best wishes.
