I am going to put the blame on the instructor and give the students a pass. The reason you take the class is to gain the information, and details of the instructional requirements are not always that easy to find. In Minnesota the instructor and course details are vague enough that it takes most instructors multiple tries to get their course approved, and BCA will tell you where you are lacking, but they do not tell you what they want.
This is the reason I like to take classes with multiple instructors. When there is a difference I can question them, and if I don't like the answers I can dig deeper.
