Recently we got a question. "On the quizzes, can it be set so that if the learner fails a quiz they cannot move forward in a video?"
Yes - that is supported out of the box.
When you are configuring a Quiz,
1. Set "Gate:Y"
2. Under Options / Review Screen, uncheck "Allow viewer to see correct answer(s)"
3. Under Options / Pass/Fail Actions, Set On Fail / Jump to Time to 0 seconds and check "Reset questions"
A viewer will not be able to proceed in the video until they have correctly answered the question.
Here's a simple example.
