They get the official course name only.
ex. Bio 101: introductory ecology and evolutionary biology
Bio 102: introductory cellular and molecular biology
So depending on the official course title, they may be able to tell what its about. I do remember there were a few courses of mine (usually non-science) where you couldn't really tell what it was about.. oh well.
I didn't have to dispute a course categorization, so I'm not quite sure how that would work.
