OET speaking is built around role plays: you take your professional role and talk with a patient or a relative in a realistic situation. Clear explanations, empathy and structure all count.
These articles explain how the role plays work for nurses and doctors, how to structure a conversation, and how to practise with realistic cards and recordings of your own answers.
