You should sign the admit card exactly as done in the registration form.
This is important because your signature must match official records.
A mismatch in the signature can cause issues during exam verification.
It can also create problems later with the result, certificate, or admission.
Avoid using the signature done in LOC if it’s different from the registration one.
Carry the same signature to the exam hall and future documents.
When in doubt, contact your school or board authority for confirmation.
