This is a revision book intended primarily for candidates sitting their MRCP Part 1 examination and which covers all the essential basic sciences. It focuses on the recurring themes which come up in the questions. The book also includes a chapter on clinical pharmacology (which alone accounts for up to 30 percent of the questions), looking at aspects of drug-induced disease and drug interactions. Finally there is a chapter on statistics and epidemiology which is rarely covered in other texts, but is often included in the exam. Despite the changes to the teaching of the undergraduate in medicine and the integration of the basic sciences with clinical education, the junior doctor, faced with postgraduate examinations, is always going to be poorly prepared for those increasingly important subjects. This book presents the essential information in the form of lists, tables, diagrams and flow charts.
