> Listing anything on a Resume is never pointless

Sorry, but you have absolutely wrong ideas about resumes, how they are read, and what information they convey. Both descriptively and normatively.

> Courses like the one mentioned are open, which means if you wanted to test that knowledge you could, easily.

If I have to test anything, I'm going to test the actual job skills. But actually the point of a degree/certification/whatever on a resume is to show me that someone else already did the testing so I don't have to spend time doing it. Conversely, if I have to test it again, it's pointless to put on a resume.
