No it is impossible to get NIT college at 82 percentile NTA score because it is very low score it means that only 82% students are behind you so suppose there are 10 lakh  students appeared for the exams send your rank would be around 180000 so it is impossible to get in NIT college at 180000 rank your rank must be within top 20000 to get a good and it so I think you need to score more than 98 percentile should try better the next attempt.
