Whether you work as an examiner or not, how do you feel in a test situation when you see nervous students in front of you? Do you sympathise? I sincerely hope that the preparation course they took was similar to what David Petrie described in his IATEFL 2017 presentation (so sorry I missed it!). Having subject knowledge, task knowledge and, perhaps most importably, self-knowledge – this is what can really help the candidates. Perhaps we are all ‘exam whisperers’, teachers and examiners alike?
