Dear Aspirant,

80 percentile is quite low for getting into an NIT. If any student wants to get admission in an NIT then his/her percentile must be at least 97. At 80 percentile, your rank is about 1.7 lakhs which is calculated by the method given by NTA that is {100-(your percentile)}*8744.69.

Even if your in OBC category and also a female admission in any NIT is next to impossible at this rank. 

You can look for some other colleges like the University of Kurukshetra and some private colleges like Manipal Institute of Technology and various others. For more details of colleges available at your rank, you can visit the career360s college portal.

Also, I would suggest you must focus on improving your percentile in the coming jee mains April paper rather than worrying about the colleges you will be getting as you will get plenty of time to do so at the time of counselling in the month of June.

All the Best for your mains.
