 Some of the mistakes included a Physics question where the incorrect unit of measurement was used, a history exam where an image was labelled 1915 instead of 1925., a mathematics exam where an incorrect answer had been given in an example question, a music exam where questions were asked that were not in the subject syllabus.Other more serious blunders by the Council included a printing error in an economics exam where questions from the history course had been included and an exam supervisor allowing students to use notes when they were not supposed to.In another instance of outright incompetence a food science and technology exam had to be rewritten after it had been displayed on the Council web-site for two days.
