This claim pops up often on forums. MMIs can feel chaotic: you move quickly between short stations, each with a new question, task, or role play. Many students come away thinking “it’s all luck.” But while stations do vary between schools, the format isn’t random at all.

✅ Yes, there is variety

• Each medical school designs its own set of stations.

• Topics can range from ethics to role play to data interpretation.

• You don’t know exactly what will come up on the day.

That unpredictability can make it feel impossible to prepare.

❌ But MMIs aren’t a lottery

MMIs use repeatable station types that are deliberately standardised. You’ll almost always encounter a mixture of:

• Role play (breaking bad news, dealing with conflict)

• Ethical dilemmas (confidentiality, resources, fairness)

• Prioritisation scenarios (ranking tasks under pressure)

• Communication tasks (explaining something clearly, giving instructions)

• Reflection on your experiences and motivation

The scoring rubrics for each station are structured. Interviewers are trained to mark specific traits, not random impressions.

🧾 What interviewers actually score

They want to see how you:

• Communicate clearly and calmly

• Show empathy and professionalism

• Structure your reasoning

• Stay composed under time pressure

They’re not looking for perfection. They’re looking for consistent skills across the circuit.

💡 Strategies for preparation

• Practise station types. Use mock MMIs or online scenarios to rehearse.

• Time yourself. Get used to 2 minutes reading, 5–7 minutes speaking.

• Use frameworks. STARR for experiences, PEE for short questions.

• Work on recovery. If one station goes poorly, reset before the next.

✅ Key takeaways

MMIs may feel unpredictable, but they are not random. You can prepare for the common station types, practise timing, and develop the skills interviewers actually score. Preparation makes a real difference.
