This book includes MCQs in the basic sciences that underpin the study of obstetrics and gynaecology, as is examined in Part 1 of the membership examination. Following the syllabus recommended by the RCOG, the questions are arranged in papers of 60 questions, each question having 5 stems with True/False answer options. Full answers with explanatory text will be provided. Where appropriate the answers will be supplemented by key message boxes and footnotes to direct further study - in this way the book can be used as a study guide as well as a tool for revision and self-assessment. A unique feature of the book will be the accompanying CD-ROM. Using this the candidate will be able to select at random questions to make up a practice paper which they can sit under 'examination conditions'. When the candidate has completed the mock examination the program will calculate their scores and indicate whether this would represent a 'good pass / pass / borderline pass or fail'. As with the text, full explanations of the answers will be provided. (saji)
