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.
