The seminars are compulsory and the course convenor runs them all and is very strict about arriving on time, professional appearance, etc. They are basically run to improve your communication skills. Most of the time, you'll have a scenario with actors and you have to answer the patient's (who is the actor) questions or find out why exactly they have bad oral hygiene, etc. You are given a time limit, which is usually 3-4 mins and you have to complete the scenario within that time frame. The marks you get in these scenario count quite heavily towards your final mark. Hope that helps.
In regards to 1040DOH, does anyone know what the seminars are like?
Are they similar to lectures? Is attendance compulsory? The course profile doesn't elaborate much.
