QUESTIONS & ANSWERS SERIES The Q&A series is a publishing phenomenon, with total sales now exceeding well over 750,000 copies. This success has been achieved by following the Cavendish Publishing principles of providing students with the text they need, at a price they can afford. Each Q&A contains 50 questions on topics commonly found on exam papers, with comprehensive suggested answers. The titles are written by lecturers who are also examiners, so the student gains important insights into exactly what examiners are looking for in an answer. This makes them excellent revision and practice guides. The books emphasise a clear, logical approach to answering questions, concentrating on form as well as content. The books are organised by topic, with the introduction to each chapter outlining the main points of knowledge needed before questions in that chapter can be answered. Each answer also includes supplementary notes that highlight points of particular difficulty, or which refer to additional or alternative material.
