When your audience completes an activity, they'll see a completion screen that shows how well they did on that specific activity.
At the end of an activity, a user will see a screen that displays their results. It displays the total number of points, and what you earned. In this example, the learner may want to try the activity again or they can move on.
Remember, this isn't a high stakes exam. Some people might want to try to score higher on an activity by trying again, while others may choose to move on (and that's okay).
