IES Main Exam Pattern (UPSC Indian Engineering Services )
The IES Main Examination consists of two papers, both of which are discipline-specific.
Paper 1: Engineering Discipline-specific
- Duration: 3 hours
- Maximum Marks: 300
- Questions: Conventional (essay and descriptive type) questions
- Syllabus: Advanced topics and chapters specific to the chosen engineering discipline.
Paper 2: Engineering Discipline-specific
- Duration: 3 hours
- Maximum Marks: 300
- Questions: Conventional (essay and descriptive type) questions
- Syllabus: Further advanced topics and chapters related to the chosen engineering discipline.
Syllabus for IES Main Examination (Engineering Discipline-specific):
The syllabus for Paper 1 and Paper 2 is discipline-specific and covers advanced topics and chapters based on the candidate’s chosen engineering discipline (Civil Engineering, Mechanical Engineering, Electrical Engineering, or Electronics and Telecommunication Engineering).
Candidates should refer to the official UPSC IES notification for their specific engineering discipline to access the most up-to-date and detailed syllabus.
The UPSC Indian Engineering Services (IES) examination is conducted in multiple engineering disciplines. Below, I will provide a more detailed syllabus for both the IES Preliminary Examination and the IES Main Examination, including specific topics and chapters that are typically covered. Keep in mind that the exact syllabus may vary slightly from year to year, so it’s essential to refer to the official UPSC notification for the most up-to-date information.

UPSC IES Syllabus Main Examination
The IES Main Examination consists of two papers, and the syllabus is discipline-specific based on the candidate’s chosen engineering discipline. Here’s a general overview:
Paper 1: Engineering Discipline-specific
This paper focuses on the candidate’s chosen engineering discipline. The syllabus typically covers advanced topics and chapters specific to the selected engineering branch.
Paper 2: Engineering Discipline-specific
The syllabus for Paper 2 is also discipline-specific, covering further advanced topics and chapters related to the chosen engineering discipline.
Candidates are encouraged to refer to the official UPSC IES notification for their specific engineering discipline for the most up-to-date and detailed syllabus. Preparing thoroughly with standard textbooks and previous years’ question papers is crucial for success in the IES examination.
