Hello aspirant!
With an 82 percentile in JEE Mains and an OBC-NCL rank of around 89,000, getting admission into NIT Durgapur will be quite difficult, especially for popular branches like Computer Science, Electronics, or Mechanical. These branches usually close much earlier for both general and OBC-NCL categories under the home state quota.
However, you might have a slim chance in less preferred branches like Biotechnology, Metallurgical, or Mining Engineering, particularly during the CSAB special rounds. So it's still worth applying and keeping those rounds in mind. Sometimes unexpected vacancies open up.
