IES Syllabus for ECE | UPSC IES 2019


The Indian Engineering Services Exam is conducted to recruit engineers in various government departments. ECE is one of the branches of engineering that is optional in this exam. In this post, we would talk about the topics in IES Syllabus for ECE. So, without wasting much time, let’s get straight to it.

IES Syllabus for ECE – Exam Pattern

Before knowing the IES Syllabus for ECE, we think that you should first know about the UPSC ESE Selection Process. The overall selection process involves three stages:

  • STAGE 1: Preliminary Exam
  • STAGE 2: Mains Exam
  • STAGE 3: Interview

You need to qualify the Preliminary Exam to appear for the Mains exam. Similarly, you need to pass the Mains Exam to appear for the Interview. However, the total marks in all the stages would be taken into account to prepare the merit list.

IES Syllabus for ECE – Exam Pattern

Let us now take a look UPSC IES Exam Pattern details. Since the prelims stage is the first stage of the exam, let us first look the exam pattern for IES Pattern 2019.

UPSC IES Exam Prelims Pattern

The following table gives the details of the UPSC ESE Exam Prelims Pattern.

Subject Duration Maximum Marks
Paper-I (General Studies and Engineering Aptitude) 2 hrs. 200
Paper-II (Engineering Subject) 3 hrs. 300
Total 500

Important Things to Note About the UPSC ESE Prelims Exam

  • This paper would be MCQ Test
  • You would get 1 marks for every right answer. For every wrong answer, 0.33 marks would be deducted from your score.
  • The Paper II would be an optional paper. You would be able to choose from the following engineering streams as your subject from Paper II.
    • Civil Engineering
    • Mechanical Engineering
    • Electrical Engineering
    • Electronics and Telecommunications Engineering.

UPSC ESE Mains Pattern

Let us take a look at the mains exam pattern for UPSC ESE 2019. The following table gives the details:

Subject Duration Maximum Marks
Paper-I ( Engineering Subject ) 3 hrs. 300
Paper-II (Engineering Subject) 3 hrs. 300
Total 600

Important Things to Note about the UPSC ESE Mains Exam

  • Unlike the prelims, the mains would be a conventional type paper. To put it simply, you would have to write long answers.
  • The questions would be set in English and you have to answer in English only.
  • Both the papers, Paper I and Paper II, would be on the same engineering subject.
  • You would get the option of choosing from the following streams as your Engineering Subject.
    • Civil Engineering
    • Mechanical Engineering
    • Electrical Engineering
    • Electronics and Telecommunications Engineering.
