In cases where the number of candidates exceeds the available seating capacity in a single session, it becomes necessary to divide them into multiple sessions. Another factor that may lead to multiple sessions is the occurrence of technical disruptions, such as power failures, network problems, or computer malfunctions, and they can affect an entire examination centre or specific candidates. To mitigate such disruptions' impact on the examination's fairness, affected candidates may be rescheduled to take the exam in an alternate session or on a different day.
