The examination body said it made the decision owing to the discovery of certain infractions such as use of strange biometrics during the registration process.

The registrar of the examination body, Professor Ishaq Oloyede, who cited some of the affected cases in a statement made available to our correspondent on Wednesday morning, stated that some registration officers in the affected 178 Computer-Based Test centres added their fingerprints to complete the registration process for the candidates.

The former Vice-chancellor of the University of Ilorin, however, mentioned that the 817 affected students would be given another opportunity to re-register for the exam with the centres bearing the cost.
