You can view general details of a user's completion tracking in the User Progress tool.
If you access the Content section in the User Progress page, you can track how many visits a user makes to the Content tool, how much time is spent viewing course material, and how many topics were visited. Expand the report details under each module to find a further breakdown of a user's actions. The expanded details show all topics and sub-modules within the module, how many visits the user made for each topic, and how much time was spent in each topic. Clicking on the module or topic's name brings you to that module or topic in the Content tool.
The Progress Summary page displays, showing overall user progress results for the current course. To only view Content results, from the course side panel, click Content.
