In the Listening exam of 2007, there was a part asking students to determine whether marked sentences were correct or not, based on the whole recording. There were 10 questions, carrying 2 marks each. In that part, if a candidate answered a question correctly, 2 marks were awarded but if the question was answered, 2 marks were deducted. No marks were given or deducted for blank answers. A candidate who answered all the questions, with no more than 5 being correct, would end up having no marks for that section, but if 5 were correct, 10 marks were given. That stirred up controversy among candidates, who claimed that the marking scheme was not fair. They said that all questions were compulsory so there should not be any advantage to those who left some of the blanks empty by deducting marks for wrong answers. The HKEAA said that it had been in practice for years to prevent students guessing answers, but in fact, this type of marking had appeared only in table-type questions in which candidates were required to tick some of the boxes in the table but not in questions in which all blanks were to be filled.
