ESE 2025 Electronics & Telecommunication Engineering Syllabus and Books

The Engineering Services Examination also referred to as ESE, is one of the major examinations conducted by UPSC. Each year, thousands of aspirants appear for this exam and clear the subsequent stages of the exam, i.e., prelims, mains, and the personal interview round, to serve in various departments of the Government of India as designated officials in the respective government departments.

What is ESE Electronics and Telecommunication Engineering?

Electronics and Telecommunication Engineering is one of the top engineering streams that forms part of the Engineering Services Examination (ESE). This is one of the most challenging exams for engineering students in the government sector, especially for engineering graduates and students belonging to Electronics and Telecommunication Engineering background. The selected candidates receive selection at some of the top government organizations in the railways, naval, telecom, and power engineering sectors for the Grade A and B posts.

What is the ESE Electronics and Telecommunication Engineering Syllabus 2025?

The ESE 2025 Syllabus associated with the Electronics and Telecommunication Engineering subject is as follows:

ESE Syllabus Preliminary Stage-I Examination: Electronics and Telecommunication Engineering (E&T)

The standard of the paper in General Studies and Engineering Aptitude (Preliminary Stage-I Examination) will be as may be expected of an engineering or science graduate. The standard of papers in other subjects will approximately be that of an engineering degree examination at an Indian university. There will be no practical examination in any of the subjects. One must keep the following points in mind concerning General Studies and Engineering Aptitude (Preliminary Examination/Stage-I, Paper-I, Objective Type, Common to All Candidates):

Current issues of National and International importance, relating to Social, Economic, and Industrial Development.
Engineering Aptitude covering Logical Reasoning and Analytical Ability.
Engineering Mathematics
Numerical Analysis
General Principles of Design, Drawing
Importance of Safety
Standards and Quality practices in Production, Construction, Maintenance, and Services.
Basics of Energy and Environment: Conservation, Environmental Pollution and Degradation, Climate Change, Environmental Impact Assessment.
Basics of Project Management
Basics of Material Science and Engineering
Information and Communication Technologies (ICT) based tools and their applications in Engineering such as Networking, E-Governance, and technology-based education.
Ethics and Values in the engineering profession.

ESE 2025 aspirants must remember these points associated with the ESE Syllabus for Electronics and Telecommunication Engineering.

*Note: The paper in General Studies and Engineering Aptitude will include knowledge of relevant topics, as may be expected from an engineering graduate, without special study. Questions from all the 10 topics mentioned above shall be set. The marks for each of the topics in both papers range from 5% to 15% of the total marks in the paper.

The contents of the syllabus for both papers are together for the preliminary examination (Stage‐I) and separately for the mains (Stage‐II) examination. The preliminary examination associated with the ESE 2025 syllabus comprises mainly the objective type Paper-II. The next part of the ESE 2025, i.e., the Mains Examination, comprises the conventional types Paper-I and Paper-II.

This segment is all about tips on how to manage your time, especially when you have a brief idea of what to study and where to study:

Set a realistic schedule- To reach your goals, start by creating a time schedule and sticking to it. However, making a realistic and practical schedule is very important. Everyone has a better understanding of their study schedule. It is advisable to set a realistic time that you can follow. A realistic schedule will motivate you to study, and it’s important to include breaks in your timetable. Coming back with a fresh mind will not only help you tackle difficult topics but also help you achieve success in your exams.
Divide and conquer- Follow the strategy of dividing the larger topics further into subtopics. In that way, it will help you complete the topics easily and on time. Begin with topics you find easy to understand to boost your motivation. This strategy is very helpful with difficult topics, as they are time-consuming, so you have the required time to complete certain difficult topics.
Don’t Get Stuck for Too Long- When a topic is difficult, students tend to give it more time but don’t realize the time constraint. Instead of getting stuck, take breaks to revise what you’ve already learned or move on to new topics. Returning to difficult subjects with a fresh mind after a break can help you understand them better.
Try mock tests and past-year questions- Attempting the mock test and previous-year questions of ESE Electronics and Telecommunications will give you a brief idea of the real experience of the exam and the time constraint. Instead of getting stuck, take breaks to revise what you’ve already learned or move on to new topics. Returning to difficult subjects with a fresh mind after a break can help you understand them better.
Know Your Subjects and Syllabus- In this blog, we have given the syllabus and concepts that need to be covered. One is very familiar with the syllabus and topics, and this will further help you to divide the topics that are easier, concepts that require less time, and topics that are difficult and also time-consuming. Allocate the time to the topics that are prior to study based on their weightage and importance in the exam.
Stick to your plan- As stated above, everyone is aware of their study pattern and environment. So make a realistic plan, as you know the best possible way to achieve your goals. Everyone will give their tips, advice, and suggestions regarding the preparation. Although listening to them is good, following and sticking to your plan is essential. Minimize distractions, and if you feel your plan isn’t working well, make small changes within a four-week timeframe to see progress.

Hope this blog post helps you ace ESE 2025 Electronics and Telecommunication Engineering Exam, which will help you begin your preparation and march in the right direction in your career.

All the best for your ESE Preparation!
