I used to be a senior moderator with AQA so I was party to what went on. Those of you with long memories will know that this is not the first time that this has happened. In fact it happens everytime there is a change in the exam spec. It happened when SEG and NEAB merged to become AQA - the SEG marks were made to drop by 3% every year causing an inexplicable (as far as the SEG teachers were concerened) change in grade boundaries with a resulting outcry. Similarly there was a *** up at AQA when the previous new spec was introduced causing a similar number of complaints. Exam boards are a bit like freemasons, everything is deliberately hidden; they will never admit to mistakes or properly explain to teachers why things happen; I suspect that they have to appear invulnerable otherwise the press will have a field day! Which doesn't help the poor teacher.
