So many course seem to say the same thing. When doing several over a short period of time it becomes pbvious. I am getting that "Groundhog Day" feeling. Friendly, Clean, Support, Equipment Expectations etc. Four answers with three close and one should ring out above all others. The answer should be more directed to fine the answer right in the book. In the trades there is shades of grey.
The use of reviews should be incorporated more into the courses because it serves as an evaluation for the student, instructor and course. The reviews will allow you to make adjustments as needed and to help guide the students progress.
Review of material is always good for both teacher and students and need to be done on a regular basis.
