Hi aspirant

82%ile is too low to get into NITs.

For NITs/IIITs/GFTIs you need more than 96%ile.

You can get state engineering colleges .You must be knowing form this year onwards almost all state engineering college will take admission on the basis of JEE mains marks .So you should apply for state counselling.

Use college predictor tool to predict you colleges: https://engineering.careers360.com/jee-main-college-predictor
