I didn't take it, but the materials they give you are pretty good (saw someone else's after they came back from the course) - nice powerpoint reviews of different areas. They looked like they would be good for boards study, particularly some of the CP stuff. The quality and completeness of each powerpoint seemed to vary greatly based on the presenter though. From what I hear, it is perhaps not quite as boards-focused as the osler course (although it is still intended to be useful for that purpose) because there is a little more practical info in it.
