yep our friends married in the church had to go to the course. from what i rememeber of them telling me it was just asking each of them seperately about how many kids they want/who will raise them, who will be bread winner, etc. probably stuff people should think of or talk about before that stage in a relationship.
i however was married by a celebrant at a beach - no such course. we had a chat with her and a quick run through the ceremony a few weeks out. but our vows/promises to each other included stuff about me being able to spend money on cars and play xbox as long as she could spend what she wanted on hair products, etc.
