IES Electrical Engineering Preparation Strategy

How to prepare for IES Electrical Engineering (ESE - IES)

Engineering Services Exam is not a difficult exam if you prepare and approach in the right way. If you are an aspirant preparing for IES exam with electrical engineering stream, we share you the right approach for your exam preparation in this article to achieve your dream job in central government engineering services.

How to start IES Electrical engineering preparation?

Start your preparation with a detailed analysis of question paper trends and exam pattern changes over the last few years. Before starting your IES electrical engineering preparation, refer the IES Syllabus for electrical engineering stream, the syllabus of IES and your B.E syllabus overlap with 50-60%. So, have a good idea of UPSC IES syllabus.

Once you have understood the syllabus, refer the last 10 to 15 year UPSC electrical engineering questions papers for both subjective and conventional papers. In the initial stage, don't try to answer the questions instead try to understand the nature of questions asked by UPSC. So you know the kind of questions asked by UPSC, you will come to how to approach and prepare your electrical engineering subjects.

UPSC doesn't check your memory skills. Instead, it gives importance to the understanding ability of the candidates. So while preparing for IES provide importance to conceptual knowledge than plain reading.

Finally, give equal importance to both Prelims and Mains exam, for Prelims exam give more mock tests and practice previous year question papers. For mains, try to develop a habit of practising one to two questions on a daily basis. Also, maintain your short notes and formulas for quick revision before the exam.

New call-to-action

IES Electrical Engineering Topic wise preparation strategy

Engineering Mathematics

From this section, there will be roughly 8 to 10 questions are asked IES prelims. Most of the questions are asked from Matrix theory, Eigen values and linear equations.

As you are aware, UPSC gives important to all sections. Don't prepare only a few topics but prepare comprehensively and have a good command over formulas and shortcuts to solve the problems.

Electrical Materials

This section provides good scoring opportunities in electrical engineering. Prepare from standard textbooks and for some recent update refer online sources apart from standard textbooks.

Electric Circuits and Fields Circuits

Electric circuits and Fields is core section of electrical engineering, in this section try to understand the important theorems and laws like Gauss, Norton s, Thevenin s and Biot-Savarts, Maxwell s equations etc.

Instead of memorising, try to understand the concepts clearly and find the real-time application of engineering concepts in life, as most of the questions asked by UPSC are more of application in nature. Understanding the core concepts will be helpful for writing mains answers.

Computer Fundamentals

It is an important section, roughly 8 to 10 questions are asked in Prelims exam from this section.

Topics like Number System and Boolean algebra are given more stress in this section. Basically, this section will check your understandability of computer basics in detail.

Power Electronics

In this section try to cover all the derivations especially for derivations that come in rectifier and inverters. At first, you should give importance to understanding the concepts. For numerically related try to solve the questions provided at the end of the chapter. Apart from that, solve all the example provided in the book and materials and don t just read instead practice more.

Analog and Digital Electronics

Diode, transistors and Amplifiers you can refer any book, for other topics try to refer from JB Gupta book. For numerical problems you need to refer previous year papers since JB Gupta book doesn t have questions for practice. The most important aspect in this section is you should take care of the proper usage of symbols in the conventional answer writing.

Systems and Signal Processing

In this section, there are a lot of formulas you need to remember, so keep your formula notes handy which will be helpful for your final revision. For other topics in Signal Processing, refer to Oppenheim s book on Digital Signal Processing.

Control Systems

Nagrath and Gopal book is enough to prepare this section of the syllabus. It is not necessary to read the entire book, try to cover all the topics mentioned the syllabus. For Prelims and Mains answer writing, refer to the previous year's papers for this section to understand the kind of questions asked by UPSC in engineering services exam.

Power Systems

For this section, you can refer it from Nagrath & Kothari. This book covers most of the topics provided in the power system syllabus. For numerical questions solve all the questions provided at the end of each chapter.

To score a good score in IES Electrical engineering, practice more numerical problems in all sections and try to revise the important derivations before the exam. While answering theoretical questions do mention the important advantages and disadvantages depending on the demand of the questions. Finally, the essential aspect of electrical engineering is the proper usage of symbols and mentioning units accordingly.

Basically, to ace Electrical Engineering, practice numerical problems and revise your derivations well. Do not forget to memorise the advantages and disadvantages wherever relevant for answering theoretical questions. When you write answers, always mention which symbols stand for what and express your answers in the correct units.

All the Best!
