Ten minutes with this sheet before a mock test is enough to reset your instincts for situational and rule-based questions.

## The Priority Ladder

| Rung | Principle | Rules out |
|------|-----------|-----------|
| 1 | Legality and constitutional values | Illegal shortcuts, force without authority |
| 2 | Safety of life, urgent need | Waiting for paperwork in an emergency |
| 3 | Public over private interest | Favours to the influential |
| 4 | Protection of the vulnerable | Ignoring children, elderly, sick, disabled |
| 5 | Fairness and due process | Punishment before inquiry, secrecy |
| 6 | Long-term solution | One-time patches |
| 7 | Proper channels | Passing the buck; acting beyond authority |

## The Five Option Types

| Type | Signal words | Verdict |
|------|--------------|---------|
| Passive | ignore, wait, leave it, their choice | Usually wrong |
| Aggressive | immediately suspend, forcibly, punish | Usually wrong |
| Evasive | refer to superior and wait, not my job | Usually wrong |
| Populist | agree to all demands, bend the rule | Usually wrong |
| Balanced | persuade, ensure, inquire, inform, prioritise the vulnerable | Usually right |

**L**egal · **A**ct promptly · **W**elfare of the vulnerable · **F**air and transparent · **U**nderstanding (empathy, dialogue) · **L**ong-term fix

## Rule-Based Problems

| Situation | Rule |
|-----------|------|
| Eligibility with exceptions | Grid of candidates × conditions; apply each exception only to the condition it names |
| "Data inadequate" | Only when a fact needed for the decision is missing |
| Committees | Fix mandatory members, strike out barred pairs, test conditional ("if X then Y") links |
| Scheduling | Cross out each person's unavailable days; the common free day is the answer |
| Task sequencing | Minimum time = longest chain of dependent tasks (critical path) |

## Traps

{{< callout type="warning" title="Three habits that cost marks" >}}
1. Picking the fastest option even when it breaks a rule.
2. Picking "inform superiors and wait" when lives or rights are at stake now.
3. Assuming a missing fact (age, income, marks) in eligibility questions.
