The door to Engineering Services Examination (ESE) is through previous year question papers. If an ESE aspirant is able to solve question papers in excess of 10 years, he or she is sure to clear UPSC ESE 2020 Prelims exam with good marks. IES Master Publication’s Civil Engineering ESE 2020 Topicwise Objective Solved Paper-I gives detailed solutions for the past 25 years question papers. Unlike other ESE solution books published by some of the leading institutes/publishers, the solution book from IES Master Publication offers topicwise descriptions. The main emphasis is clearly on the understanding of concepts and building upon a holistic picture. So as an ESE aspirant finishes a topic, for instance, Strength of Material, he or she will find all the previous years’ question papers with detailed explanation under that particular topic.
