Branch-wise Competition Analysis
Historically, Mechanical and Electrical engineering branches account for the bulk of the 450 vacancies. While these branches offer more seats, they also witness the highest volume of applications, leading to intense competition.
Chemical Engineering, while having fewer overall seats, often features a more niche applicant pool. Strategic framing requires you to prioritize your core branch fundamentals over general aptitude if your target refinery has a high intake for your specific discipline.
Topic Priority Breakdown
- ▸Mechanical: Thermodynamics, Fluid Mechanics, and Strength of Materials typically account for 40% of the paper.
- ▸Electrical: Power Systems, Electrical Machines, and Network Theory remain the high-yield pillars for PSU exams.
- ▸Chemical: Mass Transfer, Heat Transfer, and Thermodynamics are the non-negotiables that form the core of the technical section.
30-Day Preparation Roadmap
Week 1 focuses on building core conceptual strength. Dedicate 6 hours daily to clearing backlogs in high-yield subjects. Week 2 involves active revision and subject-wise sectional tests to identify your weak spots. Week 3 is strictly for full-length mock tests to build speed and accuracy. The final week involves review of errors and revision of short notes.
