Arya, you need to mention your overall JEE Mains rank because the link which I am mentioning below in that the cut-off rank which is mentioned in each category is overall JEE Mains 2017 rank. I assume your overall rank must be around 50,000 so with this rank you will have a pretty good chance to get admission in DTU if you belong to Delhi region. Even if you belong to outside Delhi region with this rank you can still get a very good branch.

You can go through the link mentioned below and check out the 2017 cut-offs of the 6th round in DTU:

Feel free to ask if you have any more queries. All the best!!
