hello asif!!

congratulations for scoring good marks in RRB .

As you have given your category as EWS, till the time of document verification you have time to get the EWS certificate proof.By then please kindly make sure to have the certificate anyhow.

If not able to get , then kindly score very good marks so that you clear the exam with more marks than the open category cutoff. Wait for further stages , if they give any option for corrections, if not then during document verification you will have a slightest chance to put forward your problem there and it will lie upto the authorities discretion whether to accept or not.

rest hope for the best

thank you and all the best
