In 2014 the loss of an A-Level Core Mathematics C3 Mathematics exam being delivered to an international school in Amsterdam led to a replacement paper being published for the Summer examination series; however, 60 students in the UK took the original paper due to it mistakenly being handed out in two UK and two overseas centres, while the replacement paper was taken by 34,000 students. The replacement paper was criticised for including questions that were not present on the syllabus, and that the students taking the original paper would be unfairly marked.[12]
