Hello,

You need to provide the aadhar card on the day of GATE examination in the respective examination centre. Photo identity needs to be provided to verify your identity whether the same Applicant is appearing for the entrance or not. So you do not have to worry if the name is wrong as you have affidavit stating that the name is wrong and the correct name is so and so. You can carry the affidavit, aadhaar card and GATE admit card to the examination centre.
