This book is primarily meant for those students who are preparing for AIIMS PG Entrance Exams. Our effort to come up with this current book is due to huge demand by AIIMS aspirants who are in search of quality book with genuine recall of questions with correct options and most authentic answers with relevant references. Every solved question will have a valid reference citing a standard textbook or article in order to increase the credibility of the answers. The focussed explanations should help student solve questions from same topics in the future easily. Our book would serve as a true companion for all those hard working PG Aspirants with most authentic answers from highly reputed faculties. For making the book authentic authors needed crisp explanations and authentic referencing, explaining the picture based questions, each requiring expertise. The only solution was to seek help. Every chapter in this book was solved by the masters in their own subjects.  Authors have incorporated a systematic approach in solving each and every question which can be appreciated while reading this book. Authors have tried to put our best effort to give correct explanations in the right contexts covering maximum topics.  The schematic diagrams, tables, illustrations, bulleted key points and references are highlights of this book and will make reading and understanding of the material easier and effective.  All the information has been presented in a point-wise manner making it easy to remember and revise. All these questions have been solved by subject faculty of DBMCI. This is the most important point about the book unlike other books which are written by a single author, writing a book on 19 subjects. Hence, similar books by other authors have a lot of mistakes and they are not updated also.
