Key Insights from GATE Mechanical Engineering Weightage (2020-2025)
Highest Weightage Subjects
Manufacturing Engineering consistently carries the highest weightage (14-18 marks) across all years, making it the most important subject for GATE Mechanical preparation. Power Plant/Thermal Engineering (including Thermodynamics, IC Engines, Power Plant) also maintains substantial weightage (6-13 marks) and shows an increasing trend from 6 marks (2021) to 10-13 marks (2022-2025).
High Weightage Core Subjects
Engineering Mathematics (11-15 marks) maintains consistently high weightage, with peak at 15 marks in 2022. Theory of Machines & Vibrations (7-10 marks) and Fluid Mechanics (4-10 marks) are core mechanical subjects with significant weightage. Mechanics of Materials (SOM) (5-7 marks) maintains stable moderate-high weightage.
Moderate Weightage Subjects
Industrial Engineering (6-8 marks) and Heat Transfer (4-10 marks) show variation across years, with Heat Transfer peaking at 10 marks in 2022. Machine Design (2-7 marks) and Engineering Mechanics (2-8 marks) show significant variation, with Engineering Mechanics peaking at 8 marks in 2022.
Low Weightage Subjects
Refrigeration & Air Conditioning consistently carries the lowest weightage (0-3 marks) across all years, with zero marks in 2022. This makes it the least important subject in terms of marks allocation, though it may still appear in the exam.
General Aptitude
General Aptitude consistently carries 15 marks across all years and is constant. This section can significantly boost your score with proper preparation, as it tests language and analytical skills that are relatively easier to master compared to technical subjects.
Preparation Strategy
Focus heavily on Manufacturing Engineering and Power Plant/Thermal Engineering as they carry the highest weightage. Engineering Mathematics requires significant attention due to its consistent high weightage. Theory of Machines & Vibrations, Fluid Mechanics, and Mechanics of Materials are core subjects requiring balanced preparation. Don't ignore moderate-weightage subjects as they can make a difference. General Aptitude (15 marks) is constant and can significantly boost your score. Practice previous year papers from 2020-2025 to understand the recent pattern and difficulty level.

Key Takeaways for GATE Mechanical Preparation
Focus Areas
Manufacturing Engineering and Power Plant/Thermal Engineering together account for 25-29 marks (2024-2025), making them the top priority. Combined with Engineering Mathematics (13-14 marks), these three subjects alone contribute to approximately 38-43 marks, which is nearly 40% of the technical paper.
Recent Trends
The increasing weightage of Power Plant/Thermal Engineering (from 6 to 10-13 marks) and Fluid Mechanics (from 4 to 7-9 marks) in recent years indicates a shift toward thermal and fluid engineering subjects. This suggests candidates should strengthen their fundamentals in thermodynamics, heat transfer, and fluid mechanics.
Balanced Approach
While focusing on high-weightage subjects, don't completely ignore moderate-weightage subjects like Theory of Machines & Vibrations, Fluid Mechanics, Mechanics of Materials, and Industrial Engineering as they can contribute 25-30 marks combined. General Aptitude (15 marks) is a guaranteed scoring opportunity with proper practice. Refrigeration & Air Conditioning can be given least priority due to minimal weightage.
