This has come up a few times, so I'm posting this here as a separate topic that should be easier for people to find when searching.

There are some objects off the right edge of the screen in the Quiz Controller and Linear Results templates (in the Results Layer) that are only shown when that quiz is passed or failed (see attached image). You can drag them onto the page while testing, if you'd like, to see how/when they're shown, and then drag them off screen again when you're ready to deploy.

There's also a "quiz score" object that you can use to easily pull the score ("quiz score . getText").
