Electronics and Telecommunication Engineering Syllabus
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):
| Subjects | Syllabus |
| General studies and engineering aptitude | Basics of material science and engineering Engineering aptitude Standards and quality practices in production, construction, maintenance, services, and project management basis Ethics and values in engineering profession Current affairs Engineering mathematics and numerical analysis General principles of design, drawings and the Importance of safety Information and communication technology Basics of energy and environment |
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 2026 syllabus comprises mainly the objective type Paper-II. The next part of the ESE 2026, i.e., the Mains Examination, comprises the conventional types, Paper I and Paper II.

UPSC ESE Preparation Strategy
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 realise 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.
Stick to your plan: 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. Minimise distractions, and if you feel your plan isn’t working well, make small changes within a four-week timeframe to see progress.
