National Institutes of Technology (NITs) 

Government Funded Technical Institutes (GFTIs)

You may also have opportunities in some IIITs (Indian Institutes of Information Technology) and various private engineering colleges. 

With SC category rank 10939 there are high chancesof getting into one of the colleges at Delhi JAC.

You have a good chance of getting into a college in Delhi through JAC (Joint Admission Counseling) with an SC category rank of 10939, especially since you are from UP and JAC considers the JEE Main All India Rank (CRL) and not just the category rank for seat allocation. Since you are an SC candidate from outside Delhi, your chances of getting a seat in the main rounds are better than those of general category candidates from outside Delhi. 

The percentile is depend on the college and your category if you are a general category students then it is impossible for you that you can take the admission in government top colleges for aerospace engineering branch and for other information you can visit the official website of the college 

Admission to NIT Patna (CSE) requires closing ranks between 10,529 to 13,706 in JoSAA for general candidates. Since your rank is much higher than that, CSE at any NIT is not attainable in the general category.

General cutoff trends for IIITs (CSE) range from ~15,000–40,000 rank? requiring 97–98+ percentile. So IIITs are also out of reach for CSE with your current rank

No, with an 83.5 percentile, getting Computer Science & Engineering (CSE) at any NIT is almost impossible.

CSE cutoffs at even lower-tier NITs typically require 97–99+ percentile, and top-tier ones demand 99.2–99.5 percentile
