Proof to be carried with admit card printout?

Identity proof is not compulsory, its only recommendatory.  As per instructions, your photo will be there on attendance sheet.  However still its good to have other proof.  I dont think invigilator should have any problem with passport.  Any document which is legally admissible (licence, PAN, Voter card etc.) should be allowable.  You can take it.

Thanks for clarifying that Mohit..I know it says 'in their own interest', but I can't seem to find my CC papers ID card, it's probably lying around somewhere, but I did not want to waste time searching for it (i never thought I would need it after getting my EC) so as long as the passport is okay, it's fine.

One examiner asked me for my articleship ID, though I'm in PE-2 and have no such ID. What the hell can I do if such fools come and ask idiotic questions?
