Congratulations Gagandeep!

For scoring such good percentile.

This is percentile score it only tell about relative performance of candidates in their respective session.I can give you rough idea about your rank in general category using this formula.Probable Rank={100-percentile Score}×874469/100.Your rank would around32.5k.Usually under this rank candidate don't get CS and IT in such top NITs.But you can expect other branch in NITs

Wait till NTA decalres rank and raw score .NTA will declares rank and score after 2nd phase of examination.

You still have one attempt for nee mains 2019.Do well.You can.

GOOD LUCK!
