Do you want people to read the thing or not. Giving the exact course name as the title guarantees very few people will read it. Telling the potential reader there's a class few people know about has a better chance. I think we can all agree that the point of any written text is for someone to read it at some point. How many books have titles that are descriptive of the contents and not something just to get you to at least pick it up and read the jacket? How many titles of movies or music albums as well? Just so as we are all clear that your attempt to be pedantic on a title definition was very much ignoring anything but something like a news headline
