Exam error leaves a sour note A mistake in an exam paper will affect about 260 South Australian students who sat the Musicianship paper on Wednesday. The SACE Board said there was an error in part of question 26. The stems of notes in a six-bar musical piece pointed down rather than up. Dr Paul Kilvert of the Board said it would ensure no Year 12 student was disadvantaged as a result of the error. He said the examiners will let the students interpret part of the piece as either an alto or soprano line. "They could use either way so the important part here is that no student will be disadvantaged, they can answer it either way and all ways of answering that will be assessed so it's a fair assessment for the student," he said.
