Ca finals exam application - certificate of service

Hi, I would like to know whether the certificate of service as required while filing exam application form for CA finals exams required to be signed by a Member of ICAI? I have completed my articleship training period and am writing finals exam in Nov, 2017. It required certificate of service to be uploaded while filing in the form. The certificate as applicable to me, being completed with articleship period, does not have any space provided for getting it signed from a CA/ Principal. Should I get it attested before uploading ? Please help, it's urgent. Thanks in advance
