The second edition provides examination practice of multiple choice questions on the basic science for the diploma of Fellow of the Royal College of Anaesthefists (FRCA). The questions are arranged in mock papers of 30 MCQS. This will allow candidates to time themselves in answering questions similar to those they will encounter in the actual examination. Each paper is followed by annotated answers. Aimed primarily at the part 2 FRCA, many of the simpler topics will be relevant to part 1 and will provide revision for part 3. The text will also benefit candidates studying for the European Diploma of Anaesthesiology. There is a new co-editor - Peter Simpson and 15% of the questions are entirely new. Most questions have been altered or replaced. In addition, answers have been expanded.
