myself & H2B did this course. It has handy as we live in Ternure, plus it is only a one-day course at the weekend which suited us as he works in London Monday - Friday so many of the other courses just weren't feasible.
I enjoyed the course when we did it. I know a lot of people give out about them, but I thought it would be helpful. It was very relaxed, there is a priest involved in presenting one of the sections, but is not overly focused on Religion which can bother some people.
It was mostly about discussing different aspects of marriage, communication within the relationship and seeking help if you need it. They said we shouldn't learn anything new on the course, but it is more for reflection on your relationship & your expectations of marriage.
I thought it was very good, relaxed & interesting. It was recommended by some friends of ours, and I would recommend it to others - plus the sandwiches & soup at breaktime were really nice!!!
If you are getting married in a church, you should check with your priest as some only accept the Accord course, but ours was fine with it. HTH.
