i am a physically handicapped student. If i get 50 percentile what would be my rank?
Dear candidate, as you not mentioned the exam, I am assuming you are talking about JEE Mains. According to the given percentile your rank will be around 430000. On the basis of this rank, a candidate cannot get any NIT but as you belongs to reservation category you can try for a chance but I would suggest you to prepare for JEE-Advance exam because percentile given by you is sufficient to qualify for JEE-Advance for your reservation category.
In 2019, JEE-Main cut-off for PwD category was 0.11371730 percentile.
