Ca final exam form for november 2017

I have completed my Articleship in the last year. I have the Articleship completion letter that was sent by ICAI to me. In the pdf form of Certificate of Service (for students who have completed articleship), nothing is mentioned regarding getting the same signed and stamped by Principal/Member of ICAI. Can anyone please tell me whether I need to get the pdf form of Certificate of Service or Exam Form signed and stamped by Principal/ Member of ICAI for November 2017 CA Final exam? Thanks in advance.
