Example Prompt
Tell us about a time when you challenged an injustice. What did you do, and what was the outcome?
Answer Structure
Introduction & Roadmap
Frame as a meaningful example of challenging injustice, not a minor disagreement.
Situation & Context
Describe a clear incident of unfairness and why it mattered in that setting.
Actions
Detail the concrete steps taken: speaking up, gathering evidence, consulting others.
Results
Explain what changed, acknowledging both improvements and remaining barriers.
Lessons & Moving Forward
Connect insights about courage and allyship to future behaviour in medicine.
Traps to Avoid
Avoid vague narratives and self-righteous storytelling; emphasise humility.
Why This Matters
Personal stations test whether you can reflect honestly, show self-awareness, and reveal judgment through specific examples, not rehearsed stories.

Compare with a model answer

A patient asks you not to tell their family about a new diagnosis. How do you proceed?
I would respect the patient's wishes because of confidentiality, and not say anything to the family…
Follow-ups, just like the real thing
Stations continue with follow-up questions, each with its own prep and response timer, so curveballs don't throw you.
Station 2 · Main prompt
You notice a classmate copying patient notes into a personal phone during a placement…
“What would you do if they denied it when you raised it?”
