This second edition is completely revised focussing on the learning needs of the new MRCPCH Part 1 and DCH exams. It features 330 questions in MCQ, Best of Five and EMQ formats, mirroring the new exams. It includes 4 entirely new chapters: Emergency Medicine; Ethics, Law and Governance; Hepatology; and, Paediatric Surgery. The chapters are split by subject to aid revision planning. Each question has a detailed explanation so the text can be used as a stand-alone revision aid. A percentage of the material was previously published in "Essential Questions in Paediatrics for MRCPCH" Volume 1 (ISBN 1901198995) and Volume 2 (ISBN 1904627331).
