dear student,

just check whether you come under the obc-ncl, that is non creamy layer.

for reservation as a obc candidate you need a non creamy layer certificate, and you should have submitted that,

if it is not the case then double check the list and if still its not there then write a official email stating your complaint to the ssc.

the details is available in the RTI- right to information page in the scc menu.

hope this helped.
