Is examiners report important? And what is it? If Importamt how should I use it effectively? And should I read every years examiners report or only the latest one?
Although they are not as important as attempting past questions and reading the technical articles, they are useful because they do highlight what the examiner was wanting and the kinds of mistakes that people were making in their answers. They are usually fairly short and so it is worth reading a few recent ones (after you have attempted the relevant questions).
