Books & People is a publish company that is convicted to craft good books that build people.. Books & People had put in much effort into the writing and crafting of our Scan & Learn Series to be a multi-dimensional learning experience. The content of this book and the articles we curated online are meant to be educational, edifying and entertaining. At the dawn of an era where new media and traditional media meet at an intersection, this book humbly hopes to bring a new dimension to learning for students and teaching for teachers. This book is the culmination of our deep considerations of how learning could be. This book hopes to inspire students to become self-directed learners. Every practice question is written to build their knowledge and to encourage self-learning. The online resources tagged to each exercise will also encourage students to learn and read deeper beyond the written exercises. Teachers will also find this book useful as a tool for classroom discussions as well. The treasure trove of articles and videos curated online will prove to be invaluable resources for lesson plans. At Books & People, we will always strive to craft good books that build people. We hope you will enjoy this book as much as we had enjoyed crafting it.
