How do I edit the "on exit" for a pretest within the properties action?

Select one of the Pretest questions, go to the Quiz tab > Actions section and click the button to Edit Pretest Action.

You'll see a Conditional Action.

Edit the passing score percentage in the condition block, and set the Action to what slide you want it to jump to if they achieve the passing score.  Set the Else Action to Continue, or to jump to an appropriate slide where they can view the content.

Hi there

I believe there is no "on Exit" because you are expected to manipulate these using Advanced Actions.
