Subject Weightage in Indian Engineering Services IES ESE for Mechanical Engineering

The Indian Engineering Services (IES) or the Engineering Services Examination (ESE) for Mechanical Engineering is a rigorous and comprehensive examination process. This article provides a detailed analysis of the subject-wise weightage for the IES ESE, with a focus on the Preliminary and Main Exam stages.

Preliminary Exam

The Preliminary Exam in the Indian Engineering Services IES ESE for Mechanical Engineering consists of two papers: General Studies and Engineering Aptitude Mechanical Engineering. The weightage for Mechanical Engineering in the Preliminary Exam is generally around:

70-80 questions Out of 100 total questions Approximately 70-80% of the exam weightage

Main Exam

The Main Exam consists of two papers, each focusing on Mechanical Engineering. The weightage is usually as follows:

Paper 1 (Technical): 300 marks, covering core Mechanical Engineering subjects Paper 2 (Technical): 300 marks, also covering core Mechanical Engineering subjects

Subject-wise Topics and Weightage

While the exact weightage can vary from year to year, here's a rough estimate of the important subjects and their relative weightage in the Main Exam:

Subject Weightage (Approximate) Thermodynamics 15-20% Fluid Mechanics 10-15% Machine Design 15-20% 10-15% Theory of Machines 10-15% Heat Transfer 10-15% Engineering Mechanics 5-10% Production and Operations Management 5-10%

Personality Test

The Personality Test carries 200 marks and assesses candidates on various attributes, but it does not have a specific subject-wise weightage.

Note: The exact weightage can change with each examination cycle. It's essential to refer to the official notification and syllabus provided by the Union Public Service Commission (UPSC) for precise details. Preparing broadly across all subjects is advisable, focusing on both high-weightage areas and fundamental concepts.

Given the unpredictability of the UPSC, it's essential to prepare comprehensively for the Preliminary Exam. Thermo (Thermodynamics), RACSOM (Refrigeration and Air Conditioning, Refrigeration and Air Conditioning, Machinery and Scientific Operations Management), Fluid, and Machine Design have historically high weightage, not in terms of the number of questions but in terms of the depth of content. However, it's crucial to study all subjects thoroughly to ensure a successful journey in the IES ESE.
