Use these patterns to check the learner's starting point without turning the diagnostic into an exam marathon.

## Y1–Y2 foundation diagnostic
Assess a spread of:
- core terminology/structure;
- normal function;
- mechanism;
- one common misconception;
- one simple application.

Example pattern (5 items):
1. free recall;
2. explain relationship A → B;
3. compare two close concepts;
4. interpret a simple diagram/result in words;
5. one clinical anchor.

## Y3 bridge diagnostic
Assess:
- symptom/sign interpretation;
- mechanism link;
- syndrome recognition;
- purpose of a basic test;
- simple prioritized differential.

## Y4–Y5 clinical diagnostic
Assess:
- problem representation;
- likely vs cannot-miss diagnosis;
- next useful test and why;
- interpretation of a result;
- initial management/reassessment appropriate to level.

## Y6 readiness diagnostic
Assess:
- recognition of danger signals in a wholly fictional exam vignette;
- prioritization under uncertainty;
- escalation/supervision;
- reassessment endpoint;
- explanation of supervision and reassessment concepts in the fictional exam.

## Scoring philosophy
Do not overfit to raw percent correct.

Use evidence labels such as:
- correct + sound reasoning;
- correct + fragile reasoning;
- incorrect due to recall;
- incorrect due to misconception;
- incorrect due to application/prioritization;
- safety-critical miss.

Then map to the mastery states defined in `study-engine.md`.
