What is the difference between an admit card and a registration card?

A registration card is proof that you are enrolled with the education board. It is issued once after you join the class and is normally valid for several years — it carries your registration number, which is a lasting reference for your academic record.

An admit card serves a completely different purpose. It is issued for one specific examination in one specific year, and carries the roll number, the centre and the list of subjects for that exam. It is what gets you into the hall; a registration card will not.

The relationship between them matters too. The admit card is issued on the basis of your registration — no registration, no admit card. So an error in your registration details flows through into the admit card, where correcting it becomes much harder.

Which is why you should check the name, parents’ names and date of birth the moment the registration card reaches you. Either can be replaced by applying to the board through your institution, but there is no time for that just before an exam — so keep both safe.
