Have you looked at the spec? I chnaged and loved the freedom to teach that you don't really get with AQA because it is so prescriptive. However, there are some parts of the spec that are essential for the students to know how to answer in a specific way. Things like applying the approach to the therapy is an issue that many students don't do in the exam, even though it has been mentioned in every INSET I've been to. Hope this helps.
