Civil Services Examination CSE and Engineering Services Examination ESE are two of the most sought after exams in India. The entrance exams for these highly esteemed services are conducted by the Union Public Services Commission UPSC every year. Civil Services Mains is a subjective exam which demands good writing skill as well as core knowledge of the subject. Engineering students need to be familiar with the difficulty level as well as the demand of such an exam. A close and detailed scrutiny of the previous years’ question papers of Civil Services Mains Examination by the Research Development team at IES Master reveals the techniques that need to be deployed in handling the Mains exam of Civil Services. Civil Engineering as an optional subject can do wonders in CSE. It is one stream that touches upon maximum knowledge area given the vastness of the syllabus. It is this vastness and wilderness of applied knowledge that gives a decisive edge to the engineers in becoming top administrative officers. This book captures and decodes technical questions of CSE from 2003 to 2018. It is this depth in time that gives students the ability to gauze the direction and the construct of an engineer required to be a top bureaucrat. As you delve into the details of this branch and confront individual subjects numerous manifestations pile up block by block. With this final raft foundation you can build upon absolute command over the required subjects. This book also allows you to practice freely on your own as the detailed solutions guide you step by step whenever the need arises. Backed by the trust inspired by the mark of ‘IES Master’ you can safely rely on this book. IES Master Publication New Delhi PREFACE
