PMT Grade 1 quiz has some tech problems

At the bottom of this Module there’s a “Music Theory Course - Grade 1 Quiz” link that appears to be a work in progress. “What do the 2 dots represent?” and the only possible answer is “SS.” Given the placeholder answer, I’m a bit worried there was a whole quiz there and it was hacked and vandalized by some sort of Neo-nazis? Any explanation?

Hey, I think there’s a bug in the quiz. In the first question I click option 3, but it automatically goes to option 4 when I submit the quiz.

Quizzes do not appear to be working. When I click on the link, it tells me that I need to enroll in the PMT course, but I’ve already done that . . . .
