Chandigarh Police Sub‑Inspector (SI) – Foundation & Exam Strategy
Topic: Marking Scheme
1. What is a marking scheme?
- It tells you how many points you get for each answer.
- Think of it like a score sheet in a game.
- Knowing it helps you decide whether to guess or skip a question.
2. How many questions?
| Exam section | Number of questions |
|---|---|
| All subjects combined | 120 |
Every question is a separate round in the game.
3. Marks for a correct answer
- +1 point for every correct answer.
- No extra bonus for “very good” answers.
Every right answer gives you a single star.
4. Penalty for a wrong answer
| Common patterns | Penalty |
|---|---|
| Official info | 0 points – no penalty. |
| Some similar exams | ‑0.25 points for a wrong answer. |
If the game says you lose a quarter of a star for a wrong answer, you must be careful about guessing.
5. Total marks
- 120 questions × 1 point = 120 total marks.
- If the exam has no negative marking, every question is worth exactly one point.
6. Tiny Example
| Situation | Correct | Wrong | Marks earned |
|---|---|---|---|
| 70 correct, 50 wrong (no negative) | 70 | 50 | 70 |
| 80 correct, 20 wrong (‑0.25 penalty) | 80 | 20 | 80 – (20 × 0.25) = 75 |
In the first case, you only count the right answers. In the second, you lose a bit for each wrong answer.
7. Quick Cheat Sheet
| Item | Detail |
|---|---|
| Total questions | 120 |
| Correct answer | +1 |
| Wrong answer | 0 (or –0.25 in some exams) |
| Total possible marks | 120 |
8. How to use this in your strategy
- Answer what you know first – you’ll get 1 point for sure.
- Skip tough ones if there’s a penalty – guessing could cost you.
- If there’s no penalty, try to answer every question – even a guess is worth a point.
- Track your progress – keep a tally: “10 correct, 2 wrong, 8 blank” – you’ll know
