I used this to teach exam literacy in Physics but could be applied to any subject/exam board. Starter activity is matching command words to instructions. Then each group was assigned a different question from a past paper they had done. They created a guide to answering the question, which helped them to understand that their factual recall was only part of exam success as they also had to explain how the command words should be interpreted and the overall approach to the question. They then used another group's poster to answer a question.
