During the last few decades of engineering academics, India has witnessed geometric growth in engineering graduates. It is noticeable that the level of engineering knowledge has degraded gradually, while on the other hand competition has increased in each competitive examination including GATE and UPSC examinations. Under such scenario higher level efforts are required to take an edge over other competitors.

The objective of MADE EASY books is to introduce a simplified approach to the overall concepts of related stream in a single book with specific presentation. The topic-wise presentation will help the readers to study & practice the concepts and questions simultaneously.

The efforts have been made to provide close and illustrative solutions in lucid style to facilitate understanding and quick tricks are introduced to save time.

Following tips during the study may increase efficiency and may help in order to achieve success.

• Thorough coverage of syllabus of all subjects

• Adopting right source of knowledge, i.e. standard reading text materials

• Develop speed and accuracy in solving questions

• Balanced preparation of Paper-I and Paper-II subjects with focus on key subjects

• Practice online and offline modes of tests

• Appear on self assessment tests

• Good examination management

• Maintain self motivation

• Avoid jumbo and vague approach, which is time consuming in solving the questions

• Good planning and time management of daily routine

• Group study and discussions on a regular basis

• Extra emphasis on solving the questions

• Self introspection to find your weaknesses and strengths

• Analyze the exam pattern to understand the level of questions

• Apply shortcuts and learn standard results and formulae to save time
