Hello

Since your admit card doesnt have your photo as well as signature you can  paste your photograph and do your signatures in the respective areas on the printout of the admit card. After this you need to get that printout attested by a member of the Institute (member may indicate their name, membership number as well as his office stamp at the time of attesting. You need to carry this to your exam centre, in duplicate too.. I will advise you to take an extra passport size photograph to the exam centre for affixing tin th eregister at the exam centre.
