Hello,

There is no correction window for SSC CHSL 2020 application. Candidates seeking age relaxation will have to provide relevant document from the competent authority in the given format. The format is given the SSC CHSL 2020 notification. https://ssc.nic.in/SSCFileServer/PortalManagement/UploadedFiles/Notice_chsl_06112020.pdf

Please read the 7.1 para in the official notification. Since you do not have to claim age relaxation you need not to submit the relevant document. But if candidates who have opted for age relaxation couldn't submit the relevant document will not be considered for age relaxation and the candidature of such candidates will be considered under Unreserved (UR) or relevant category. So need to worry about that.
