These 108 questions have been made by a group of people who came together on line to practice making good MCQs.The style chosen is one best answer and the goal was to make questions in a clinical context that test application of facts rather than rote memorization. The questions below are a mixture of those aimed at PGs and most aimed at UGs. Multipart questions can be converted into independent questions or fractional marking may be used. Thanks are due to all participants, the subeditors (Dr N Asokan, Dr Medha Joshi, Dr Fatima Zahra, Dr Umashankar T, and Dr CBSR Prasad) who helped me, and to our fearless leader Dr Sanjay Bedi for organizing this.
