Every time, a student reads a book, there is a question regarding the extent to which he/she will gain the return on the time and money that he/she is investing. This is due to the fact that the same book is also referred by 9 lakh other aspirants who are also preparing for UPSC. So, is there anything that can help you differentiate you from them? This compilation will help you inch closer to that goal. For students as well as candidates preparing for competitive examinations, the book has nearly all-important details that would meet the level of knowledge required for preparation UPSC. It covers all the topics and the emerging technological areas that may alter the geopolitics and the existing balance of power. With experience exceeding 8 years, teaching in this field, this book is written by a subject expert who has several other academic achievements to his credit. This book is of immense importance to academics, researchers, aspirants of civil services examinations and those with an abiding passion for the subject. The language of the book is simple and the content is engaging which ensures students face no trouble during studying. Along with the same, there are previous year questions attached at the end of every chapter to help the students get an inference on what topics deserve more time and which ones relatively less. It will also give an inference regarding the source of the question, what triggered that question and relative changes in the trend and the pattern of the questions pertaining to that topic. My efforts are aimed at training the students to aim at the cornea of the round black eye of that bird to the students who are 100% dedicated to clear UPSC CSE exams. And not a vague or a muddled picture of the branches or the twigs or the leaves or the trees or the other associated birds sitting on that tree. Just like Arjuna's singular focus enabled him to achieve mastery of archery, I want my students to clear this exam in their very first attempt. This episode in Mahabharata is what inspired me the most and therefore the name of my coaching... Archer' IAS Academy.
