Hello

Aman !you have asked it is necessary any signature is necessary of somebody.no signature is necessary .

Thanks for contacting us.

HI Aman,

After downloading the Admit card there is no signature required of anybody. Please do check the Admit card because it would be written on the Admit card that a valid Photo ID proof is also required in original and for some exams Photocopy of the Photo ID proof might also be required. 

So you can enter the exam hall only by the Admit card and the Photo ID proof and Photocopy of the Photo ID proof if mentioned on the Admit card.

Best of Luck!!!
