A few things to notice in the screenshot:
- The quiz complete message says I got 83 out of 84 right, but the sidebar says there are 133 questions total.
- The choices currently displayed question (#84) is messed up.
The name of the quiz is "Things, Things, and More Things!" I believe I answered all 133 questions, and I think I chose the green-highlighted (correct) response for the question shown in the screenshot. (Though I can't say either of these things with certainty)
