The edition has been revised with some deletions and many additions. The driver for change has been the ongoing curriculum change in India to competency-based education and the book presents topics useful to teachers for delivery of this curricular model. Most of the chapters have been updated to address the contemporary curricular change, but we have retained the basic nature of the material and its conversational style. Further Reading, a number of publications which we have published on competency-based medical education and related aspects have been added.
