‘We are very sorry for the delays and disruptions experienced by some of our students sitting exams in the past two days.

‘While the majority of students had a smooth experience in very busy exam sessions, we failed to reach our own high standards in some venues.

‘Our initial reports show that issues were caused by problems with power supply at some centres and technology issues at others. We will continue to investigate what went wrong and make changes where we can in order to improve.

‘Where possible, we will continue to offer students who have had exam sittings cancelled the chance to take the examination remotely within the next few days.

‘We will do our best to ensure that students do not lose out professionally as a result of these difficulties and we are happy to refund their examination fees, if we are unable to reschedule the examination.’
