The Joint Admissions and Matriculation Board (JAMB), is planning to conduct supplementary examination for candidates who had hitches in their registration and examination processes. This was confirmed by JAMB Registrar, Is-haq Oloyede, on Wednesday while addressing newsmen. “Anybody whose biometric could not be verified will be allowed to do the supplementary examination. “As at today, 640 candidates out of 1.7million candidates did not do biometric verification, reasons being that some fraudsters registered candidates across online. “In this case, the students are not guilty of the offence and hence will be made to write the exam again under my own very eyes,” he said.
