IES Syllabus 2022: Exam Pattern and Syllabus

IES (ESE) Syllabus 2022: The UPSC IES (Indian Engineering Services) has announced 247 vacancies for the 2022 cycle. In this article, we will go over the UPSC IES syllabus for both the prelims and mains exams.

Make sure you thoroughly prepare these topics because they will be the basis for the majority of the questions. The prelims exam is objective and consists of two papers: paper 1 has questions based on General Studies and Engineering Aptitude, and paper 2 has questions based on the candidate’s engineering stream. The UPSC IES mains exam also includes two descriptive papers. The mains exam questions are entirely based on the candidate’s chosen engineering discipline. For more information, see the UPSC IES official notification.

UPSC IES Exam Preparation Tips

As the written exam has objective and subjective sections, preparation for the ESE requires both conceptual clarity and problem-solving skills. Go through with these key points.

• To simplify your studying strategy, become familiar with exam patterns, the percentage of technical and non-technical questions, and the weighting of each section.
• Make smart decisions about your study plan by consulting previous year’s question papers.
• Use reference books to better understand theory, concepts, derivations, and equations, and to strengthen your fundamentals.
• You can analyse your weak areas by practising previous year’s question papers. Identify the weak topics and thoroughly revise them. Time yourself as you work on the papers to get a sense of your speed so you can concentrate on that as well.
• The General Ability section is worth 200 points and is crucial for the Personal Interview. Maintain your General Knowledge for this section by reading newspapers, watching news channels, or surfing the internet.
