Step by Step Case Studies in Obstetrics and Gynecology allows students, residents and physicians to go through the most common scenarios in obstetrics and gynecology practice and gain longitudinal experience with 25 virtual patients. The use of consistent formatting enables easy assessment of patients’ chief complaints, history, investigations, management and follow-up. At the end of each block, there are four multiple choice questions relevant to the clinical presentation to test the learner’s clinical and basic science knowledge and understanding. These items are designed to verify whether the learner has met the learning objectives. By the end of each case study, the learner has been tested over 20 high-yield items. Twenty-five case studies with 500 multiple choice questions have explanations for positive and negative choices, and high quality illustrations and images enable subject-specific practice in the field of reproductive medicine. Each case study provides a list of learning objectives and references to allow the assessment of the learner’s performance and for quick detection of the areas that need improvement.
