How can I see which learners have completed a specific tutorial?

To filter for a specific tutorial, first  click into the settings > usage stats > user reports

Click the filter icon at the top, select the tutorial filter, and then select the tutorial you would like to pull a report for. 

Once selected, click Apply to generate a report of learners who have enrolled in that tutorial, their progress, and quiz scores. 

You can also use the "Date" filter to add an additional layer of "completion date" to your results.
