hey hima,

you should contact the JEE advanced organising institute and tell them your problrm of unavailability of certificate of EWS category. I will suggest you to contact them through Email as well as phone number provided to you. In my opinion you can give the examination as a general candidate and will be treated as general candidate for the rest of the process.

Good luck !

Yess..Wait Till the last date of Application Fill up..It is mandatory to Upload that certificate..there is no Other Option without it to submit..so Visit Nearest Jan kendra & ask them to Make Your certificate by Hook or Croom..Ow you lost the opportunity..do it fast..

Thank You
