With AQA, Unit 1 was generally better, but Unit 2 still all over the place. I'm sending one for remark, but last summer they put them down rather than up when I did that! I've kept the mp3 files though (in breach of exam regulation, I know!) and just cannot explain the wide variations between my students. One made basic mistakes (such as not conjugating verbs a few times) and got an A, whereas one of my most talented linguists, who has perfect pronunciation, does subjunctives without even thinking about it and is going on to read French at university, "only" got a B. Aside from writing a transcript of both exams and sending it to the exam board, I just don't know how else to prove that they are incompetent. Very frustrating!
