Well to be frank, I was so desperately waiting for this book because other authors' book were too inferior. Yeah I m talking about 'Conceptual Review of Preventive & Social Medicine' by Dr. Mukhmohit Singh sir. All the latest updates are covered till date. The national programs and policies are given topic wise in each chapter instead of keeping all the programs at one place which is a good thing by the way. Best thing about this book is that all the chapters are given equal justice. The chapter of immunization and vaccine is one to mention here. Well the epidemiology section was literally amazing , all the tables , the diagrams ,charts made everything so easy. One of the nightmares is biostatistics for many students ,well guys this book has covered that too in a proper way I must say. Lastly the 'good to remember' , 'must remember' and 'high yield points' makes us differentiate the importance of the data in a way what to remember first. Must must buy book. This book is best for the subject instead of memorizing the data from the same old updated edition of the named book which was the only option until now.
