Resuming course to another slide

The point of the resume function is to restart the course from wherever the learner was when they left it. 

There's no way to prevent a user from closing the browser window when they reach the Results slide, which means that's where they'll "resume" if they relaunch the course. 

However, you could nudge them toward other behavior. For example, add a message to the Results page that encourages them to go to a final slide. ("Click NEXT to save your score and complete the course.") Then, if they return, they'll resume on whatever that final slide is. If the course uses a custom menu, that slide could link to it so it'd be easy to review the content.
