can I get iiit delhi with 97.5482137 percentile any branch outside delhi general category????

HELLO MOHIT
since it is very difficult to predict the exact rank but we do have a backup> we have a formula to calculate the expected rank that is (100 – Total percentile) x 869010/100.So according to formula your expected rank for present percentile for January session comes out to be 21306  . Now the expected rank might change depending on the no of candidates appearing the april session. For ex if 12 lakh candidate appear the april session then just replace 869010 by 12 lakhs. But if you score above 85 percentile then you have a very decent chance of qualifying jee mains.

Now since the official cutoffs  for college are yet to be decided but let us analyse your chances by looking into the previous year cutoffs data.Since you are from outside delhi that means you have other satte quota
