Dear aspirant !

Hope you are doing great ! There should be signature of collector, deputy collector or tehsildar or any other concerned authorities on your ews certificate otherwise it will not be considered during the counselling process . Please modify it as soon as possible . candidates belonging to SC, ST, OBC-NCL and EWS can avail a benefit of 15%, 7.5%, 27% and 10% respectively based on JEE Main Reservation.  So don't let this opportunity to go . If any problem is there then tell us anytime .
