Hi Gavin,
Another great question! There is a way to determine if a
lesson quiz has been passed or failed, and even to get the score in an easy way. There are some secret objects off screen to the right of the page. See this forum post -
How to show or hide something when a quiz is passed or failed.So in your case, you would use "failed quiz.onShow" as your trigger to update and show your review text. I don't know if you have multiple attempts turned on for your quiz, so we just used both objects as a trigger. See attached image. Or if you wanted to show something different when they passed, you could use "passed quiz.onShow" as your trigger.
