Hi.

With this mark in JEE Main, your rank will be somewhere around 30000 to 35000. With this rank I don't think you will get admission in NIT Delhi under home state quota, as the last rank for 2017 admission in NIT Delhi was 22111 for EEE under HS quota for General category.

And in the case of NSIT, i can just say that you have chance of getting admission for 2 or 3 courses. I'll give the details of last rank admissted into various courses of NSIT in 2017 -

1. BT - 38519

2. CE - 4653

3. ECE - 17227

4. IT - 9535

5. ICE - 29232

6. MPAE - 32851

7. ME - 22980

This is the rank in JEE Main 2017, that got admitted into NSIT 2017, under Delhi region - round 6.

Good Luck.
