Hey

NSIT and DTU have reservations for the categories other than general. They do have a certain percentage reserved for your category hence ews rank is considered.

As per your rank,it could be difficult for you to get admission in either of the college in any of the branch. The past year cutoff for ews category candidate ranged from 5492 to 47962(highest for bio tech and lowest for cse) for nsut and from 18085-46064 for DTU.

But you can still apply for josaa counselling and hopefully get a college in the later rounds. You can try predict your college beforehand using this link
