Hello there,
Assuming that you are talking about NEET admit card  ,the answer is no. There is no need to staple the pages.
Page 1 contains details about the centre and self declaration form.
Page 2 contains important instructions for Candidates.
Page 3 and 4 contain  the CoVid - 19 guidelines that the candidates are supposed to follow.
So , you only need to carry Admit card along with self declaration form (undertaking) to the examination centre.
All the best!
