UPSC IES Overview

The Union Public Service Commission (UPSC) conducts the Engineering Services Examination (ESE), often referred to as IES, annually to recruit graduate engineers for various technical posts under the Government of India. Eligibility typically requires a Bachelor's degree in specific engineering disciplines – Civil, Mechanical, Electrical, or Electronics & Telecommunication – along with adherence to age limits (usually 21-30 years, with relaxations). The selection process is multi-staged, beginning with an objective-type Preliminary Examination (Stage I), followed by a conventional (descriptive) Mains Examination (Stage II) for qualified candidates, and concluding with a Personality Test (Interview - Stage III). The final merit list is based on marks obtained in the Mains Exam and the Personality Test. The ESE 2025 process is currently underway (Mains typically held mid-year), and the notification for the ESE 2026 cycle is expected later in 2025. Okay, here's a short overview of the UPSC Engineering Services Examination (ESE/IES)

UPSC IES Prelims Preparation Tips

UPSC IES Preparation Tips

1️⃣ Intensive Revision: This is the priority now. Focus on revising subjects and topics you have already studied. Avoid starting large new topics if possible.
2️⃣ Prelims Focus: Channel maximum effort towards the Prelims papers.

Paper-I (GS & Engg. Aptitude): Quickly revise Engineering Mathematics, Aptitude, and core concepts of other GS topics (Environment, Project Management, Materials, ICT, Ethics, Quality, Safety). Practice aptitude questions daily. Briefly review current affairs notes relevant to engineering/economy/environment.

Paper-II (Engg. Discipline): Revise all core subjects, focusing on formulas, key concepts, and standard problem types. Speed and accuracy are critical.
3️⃣ Previous Year Questions (PYQs): This is NON-NEGOTIABLE. Solve UPSC ESE PYQs for both Paper-I and Paper-II daily. Analyze the pattern, difficulty level, and important areas.
4️⃣ Mock Tests: Take at least 5–10 full-length Prelims mock tests (Paper-I & Paper-II) in a simulated exam environment. Analyze performance deeply to identify weak spots, time management issues, and accuracy levels.
5️⃣ Formula & Short Notes: Consolidate your short notes and formula sheets for quick last-minute revision.
6️⃣ Accuracy over Guessing: Remember the negative marking. Avoid blind guessing; focus on accuracy and confident questions.
7️⃣ Time Management: Practice solving questions within the stipulated time during your revision and mocks.
8️⃣ Health: Maintain good sleep, eat well, take breaks, and avoid burnout.

Best Books for UPSC ESE Preparation

1️⃣ Must-Haves:

  • UPSC ESE Previous Years' Solved Papers (Paper-I & Paper-II, Objective)
  • Books with detailed solutions (Made Easy, ACE, IES Master Publications)
