Chandigarh Police Sub‑Inspector (SI) – Marking Scheme
Purpose of this note – Quickly understand how marks are awarded and deducted in the Chandigarh Police SI exam so you can plan your answering strategy and avoid costly mistakes.
1. Simple Explanation
| Section | Total Marks | # of Questions | Marks per Correct Answer | Negative Mark |
|---|---|---|---|---|
| Paper‑I – General Knowledge | 50 | 25 | 2 | 0.5 |
| Paper‑II – General Science | 50 | 25 | 2 | 0.5 |
| Paper‑III – General Maths | 50 | 25 | 2 | 0.5 |
| Paper‑IV – English | 50 | 25 | 2 | 0.5 |
| Total | 200 | 100 | – | – |
- Marking – Each question carries 2 marks for a correct answer.
- Negative marking – For every wrong answer, 0.5 marks (i.e., 1/4 of the positive marks) are subtracted.
- No penalty for unanswered questions.
Why 0.5‑mark deduction?
It’s the standard “1/4 negative marking” policy used by many state police recruitment boards to discourage random guessing.
2. Key Points to Remember
| # | Point | Why It Matters |
|---|---|---|
| 1 | Total Marks = 200 | Determines cut‑off and percentile calculations. |
| 2 | Equal weight to all papers | No paper is “easier” or “harder” in terms of marks. |
| 3 | Negative marking = 0.5 per wrong answer | Impacts your strategy: guess only if you’re highly confident. |
| 4 | No marks for omitted questions | It’s always better to leave a question blank than to guess blindly. |
| 5 | Answer Sheet Format | Write the letter (A/B/C/D) in the bubble; avoid crossing out. |
| 6 | Time Management | 200 marks in 200 minutes → ~1 mark per minute. |
| 7 | Cut‑off & Rank | Usually around 44–50%; aim for at least 140 marks (70% of total) to stay safe. |
3. Worked Example
Scenario
A candidate takes the exam and gets the following results in each paper:
| Paper | Correct | Wrong | Unanswered |
|---|---|---|---|
| GK | 20 | 5 | 0 |
| Science | 15 | 10 | 0 |
| Maths | 22 | 3 | 0 |
| English | 18 | 7 | 0 |
Step‑by‑step calculation
-
Paper‑I (GK)
- Correct: 20 × 2 = 40
- Wrong: 5 × 0.5 = 2.5 (deduction)
- Net = 40 – 2.5 = 37.5
-
Paper‑II (Science)
- Correct: 15 × 2 = 30
- Wrong: 10 × 0.5 = 5
- Net = 30 – 5 = 25
-
Paper‑III (Maths)
- Correct: 22 × 2 = 44
- Wrong: 3 × 0.5 = 1.5
- Net = 44 – 1.5 = 42.5
-
Paper‑IV (English)
- Correct: 18 × 2 = 36
- Wrong: 7 × 0.5 = 3.5
- Net = 36 – 3.5 = 32.5
Total Marks
37.5 + 25 + 42.5 + 32.5 = 137.5
Result – 137.5 marks out of 200 (~68.75 %).
This score is typically above the average cut‑off, but you should still aim for 140+ marks to secure a comfortable rank.
