Excellent book; the author clearly knows what he is talking about. It's a good read, even if you aren't studying for any examination. Paper quality isn't very good, and the book can get bent and formed during delivery.
QUIET SUPERB BOOK.THE CONTENTS ARE ALONG THE ARTICLES IN OUR CONSTITUTION, SO REMEMBERING IS EASY.BEST FOR BEGINNERS OF UPSC AND ALSO FOR THOSE WHO ARE INTERESTED TO KNOW ABOUT THE CONSTITUTION WITH HISTORICAL ASPECT.
