Thx for ur reply. But right now iam having this document & moreover, i didn't noticed that the EWS limit has been changed hence not opted in mains application. pl. suggest 

Having document also won't help. It is rule by the examination committee that JEE Main category will be carried forward to Advanced. You are not alone, many are facing the same problem but the candidates who made changes at the time of JEE Main application submission or correction, got the advantage. Therefore, no provision of correction will be made as of now, according to the official notice.
