The door to Engineering Services Examination (ESE) is through previous year question papers. If you are able to solve question papers in excess of 10 years, you are sure to clear the UPSC ESE exam. IES Master’s Electronics and Communication Engineering ESE Topicwise Conventional Solved Paper-I gives detailed solutions of the question papers from the past 22 years. Unlike other ESE solution books published by some of the leading institutes/publishers, IES Master solution books offer topicwise solutions with detailed explanation. The emphasis is clearly on the understanding of concepts and building upon a holistic picture. So, as you complete a topic, for instance, Sequential Logic Circuits, you will find all the previous years’ question papers with detailed explanation under one topic. IES Master Publication makes sure that the books are fully revised and updated every year so that every year you get the best reference books for ESE preparation.
