What to Expect in the CSS Physics 2021 Paper
The Physics paper is divided into Paper I and Paper II, each carrying 100 marks. Both papers feature a mix of theoretical and numerical questions.
Topics Covered in Paper I:
- Classical mechanics and Newton’s laws
- Gauss’s law and applications in electrostatics
- Work and energy theorems
- Harmonic motion and oscillations
- Lagrangian mechanics
- Optics and wave interference
Topics Covered in Paper II:
- Modern physics and quantum theory
- Semiconductor physics and electronic devices
- Thermodynamics laws and their real-world relevance
- Nuclear physics and radiation
- Interference, diffraction, and optical instruments
- Particle accelerators (e.g., cyclotron)
Sample Questions from 2021
Here are a few real examples from the CSS Past Papers of Physics 2021:
- Discuss the applications of Gauss’s law in determining electric field distributions.
- What is a cyclotron? Describe its structure and working principle.
- Explain the laws of thermodynamics and their significance in physical systems.
- Describe the Michelson interferometer and its role in modern physics.
- Derive the expression for energy stored in a capacitor.
These questions help you identify important topics and understand the level of explanation expected.

About the CSS
The CSS (Central Superior Services) Competitive Examination is a rigorous federal level test administered by the Federal Public Service Commission (FPSC) to select candidates for prestigious civil service roles across Pakistan. The exam’s rules and regulations, covering age limits, eligibility, subjects, and quotas, are detailed in the official CSS Rules section on the FPSC’s website.
The CSS Exam Rules, issued by FPSC Pakistan, outline eligibility criteria, age limits (21–30 years), and a maximum of three attempts for candidates. The exam includes written tests, a medical exam, a psychological assessment, and an interview. Rules also define quotas, disqualification grounds, and subject selection for a fair recruitment process.
How to Use CSS Physics Past Papers Effectively
Simply reading the paper won’t help unless you approach it strategically. Here’s how to make the most of it:
- Solve questions on paper, without consulting notes first
- Time yourself to simulate exam pressure
- Check your answers against trusted reference books or online lectures
- Highlight weak areas for targeted revision
- Repeat the paper a week later to check your progress
Expert Tips for Physics Preparation
Here are practical tips from past CSS qualifiers who successfully tackled Physics:
- Master your diagrams: Always draw neat, labeled diagrams in theory questions.
- Practice numerical regularly: These are easy scoring areas if you’re consistent.
- Link theory with real-life examples: Examiners value application-based understanding.
- Balance both papers: Don’t put all your energy into Paper I, Paper II carries equal weight.
The CSS Past Papers of Physics 2021 are not just a revision tool, they’re a roadmap. They help you align your preparation with actual exam expectations. With the downloadable PDF at your fingertips, you can start practicing smarter, not just harder. Make sure you download the file, analyze the paper, and use it as part of a structured study plan.
Your consistency with resources like these will set you apart.
