What happens if you fail one subject?

The overall result is recorded as a fail — passing a board examination means clearing the minimum in each subject separately. Good marks elsewhere do not make up for a shortfall in one; the subjects do not average into each other in that sense.

The whole year is not lost, though. In the next year’s examination you sit only the failed subject — the ones you passed stand and do not have to be repeated. That arrangement is what saves you from redoing a full year’s work.

The practical consequence matters. Until you have passed every subject the certificate does not issue, and without it admission or a job application stalls. The cost is not really to the result — it is to time.

One step often gets overlooked: applying for re-scrutiny. Addition errors and unmarked questions do happen, and near a borderline they can make the difference. The application window is short, so the decision has to be made soon after results are published.
