Hello Upendra yadav ,

(Considering you are General category student)

So sorry to say being an outside delhi student your marks is not enough to get into DTU or NSIT. Even for the lowest cutoff branch in DTU that is BIotech you need atleast 17k rank and 9k in case of NSIT. And your marks may land you to a rank of about 30k.

Apart from that, you need to have 60% aggregate in PCM.

But if you are an OBC then also minimum rank is 20k atleast for DTU.

So, in my opinion chances at DTU or NSIT is pretty slim.

All the best!
