Engineering Services is one of the dream job destination for every

engineer be it UPSC Engineering Services or State Engineering

Services. With the increase in competition, increase in levels of

practice is much desirable. Moreover, it is observed that year on

year UPSC Engineering Service paper standard and pattern is

moving close to Civil Services Prelims Paper (when Engineering

Optional paper was included). Not only this it is well noticed that

previous years’ questions of Civil Services Engineering Optional

paper are modified and are sometimes asked in Engineering

Services exam. This clearly portrays practice of these questions has become very important to get an

upper edge in UPSC Engineering Services and other State Engineering Services examination. To facilitate

aspirants with practice of every possible question, MADE EASY has come up with all new book of Civil

Services Prelims previous years’ solved papers (of Engineering Optional) which will surely act as add on

practice set for aspirants.

This book is the 3rd edition and has papers of 17 years (1994-2010) with complete explanation of almost

every question, written in coherent manner. Due emphasis is made to make aspirants understand the

concept and logic behind every question. To make practice easy, the book is segregated in topicwise

content so that aspirants can learn topic and practice the questions and thereby prepare thoroughly for

the exam.

I would like to acknowledge efforts of entire MADE EASY team who worked hard to solve previous years’

papers with accuracy and I hope this book will stand upto the expectations of aspirants and my desire

to serve student fraternity by providing best study material and quality guidance will get accomplished.

Best Wishes
