Hello Rajesh,

According to the given percentile your rank will be around 4,34,505. This rank is calculated using given formula :

(100 - your percentile)*869010/100

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.

Last year JEE-Main cut-off for PwD category was 0.11371730 percentile.

Hope this helps you. We wish for your bright future.

All The Best!!
