Hey RAVI , 

The certificate needed for admission IN NSIT/DTU is your OBC  central certificate . 

Hello Ravi,

You need to submit marksheet of 10th and 12th, Domicile Certificate, Medical Certificate, Caste and Category Certificate, Government ID Proof at time of admission. If you want counseling as Delhi region candidate then you have to submit Delhi domicile certificate during JAC otherwise you will be considered as outside Delhi region candidate.

Good Luck.
