Student Unit Guides are perfect for revision. Each guide is written by an examiner and explains the unit requirements, summarises the relevant unit content and includes a series of specimen questions and answers. A Content Guidance section combines an overview of the specific unit or module and the key terms and concepts, with an examiner's interpretation so that students understand precisely what they need to understand and learn, the skills required and the potential pitfalls. A Question and Answer section provides graded answers, typically A and C, to questions which have been set to reflect the style of the unit. All responses are accomnpanied by commentaries which highlight their respective strengths and weaknesses, giving students an insight into the mind of the examiner.
