Civil Services Examination is considered as most prestigious

job in India which is being preferred by engineers now-a-days.

There was a need of good book, which contains error free

questions with apt solutions that even a begineer student can

understand. I am glad to launch the second edition of this book.

MADE EASY team has made deep study of previous exam

papers of Civil Services Main Examination and observed that

a good percentage of questions has been asked in Engineering

Services Examination, Indian Forest Service Examination as well as State Services Examination.

Therefore it is advisable to study this book before one takes the exam. This book is also useful for ESE

Main appearing candidates and other competitive examinations for engineering graduates.

The second edition of this book is prepared with due care to provide complete solutions to all

questions with accuracy. I would like to give credit of publishing this book to MADE EASY Team for

their hard efforts in solving previous years papers in a limited time frame.

I have true desire to serve student community by providing good source of study and quality guidance.

I hope this book will be proved as an important tool to succeed in competitive examinations. Any

suggestions from the readers for improvement of this book are most welcome.

With Best Wishes
