Hello  Prakhyat chaubey

I hope you are doing good. I would like to tell you  that at 80 percentile candidate estimated rank will be around 204000 . At this rank candidate will hold very low chances of getting admission in NIT,IITS .Your target should be atleast to score above 95 percentile to get admission into tier one colleges which can only be done by having  a proper strategy.

you can use JEE-Main College Predictor to predict your chances of admission in different engineering colleges of India :-
