Timed Questions That Allow Learner to Choose Correct Answer but Marks the Answer Incorrect

Hello ChrisMartin-2ff​,

Thanks for reaching out!

There are many ways to approach this design, so I'll share my method, which uses Storyline 360's built-in variables. The specific built-in variable I'll be using is the Slide.ElapsedTime, which tracks the cumulative elapsed time spent on a slide. I've attached a working demo that displays a "Too Slow" layer and marks the question as incorrect if a learner takes longer than 4 seconds to answer the question.

You'll notice I forced the slide to select an incorrect response using triggers to ensure the slide marks an incorrect response after 4 seconds. The forced variable is there to control of the "Too Slow" layer will appear or not.

I'll let other community members chime in with their recommendations to give you options.
Let me know if you have any questions!
