Exam Pattern & Question Types
The PI paper consists of 65 questions totaling 100 marks. While there is significant overlap with Mechanical Engineering, the PI paper focuses more heavily on manufacturing science and optimization techniques.
• MCQ (Multiple Choice): 1 or 2 marks with standard negative marking (1/3 or 2/3).
• MSQ (Multiple Select): One or more correct options. No negative marking. Frequently used in Metrology and Material Science.
• NAT (Numerical Answer): Precise calculation required. No negative marking. Crucial for Operations Research and Machining problems.
Major Marks Distribution
The weightage in the PI paper is traditionally dominated by two major sections: Manufacturing Processes and Industrial Engineering (Operations Research).

Core Syllabus: The "Big Two" Focus Areas
To target an AIR under 100, you must achieve near-perfection in these two pillars:
1. Manufacturing Processes (30-35 Marks): Metal Casting, Forming, Joining (Welding), Machining & Machine Tools, and Advanced Manufacturing (NC/CNC).
2. Industrial Engineering (25-30 Marks): Linear Programming (Simplex, Duality), Inventory Control, PERT/CPM, Forecasting, and Queuing Theory.
3. Quality and Reliability: Statistical Quality Control (Control Charts), Process Capability, and Reliability Engineering.
4. Engineering Materials: Crystal structures, Phase diagrams (Fe-C), and Heat treatment of steels.
The Foundation: Math & Mechanics
Do not ignore the General Engineering section (Solid Mechanics, Theory of Machines, Thermodynamics) which accounts for roughly 12-15% of the paper.
• Engineering Math: Focus on Linear Algebra and Probability, as they are essential for Industrial Engineering problems.
• Mechanics of Materials: Stress, strain, and thin cylinders—essential for Metal Forming calculations.
Winning Roadmap for AIR Under 100
1. Master Operations Research: These marks are purely mathematical. If you master the algorithms (Simplex, Transportation), you can secure 20+ marks with high certainty.
2. Numerical Accuracy in Machining: Problems on Taylor's Tool Life and Merchant's Circle are NAT-heavy. Practice these daily using the virtual calculator.
3. Zero-Error in GA & Math: These 28 marks are the "rank boosters." Aim for 24+ to ensure a high base score.
4. Dual Paper Advantage: If you are a Mechanical student, focus on the differences—primarily Metrology, Quality Control, and Work Study—as these are the unique scoring areas in PI.
