Yes! If you download the report of a specific course, you can see how long the learners have spent in that course.
To do that, click on Reporting in the top navigation bar, then on Report Builder. From there, you will want to run a Course Report, then choose to display a Summary of a Course. After that, choose the Course you want to view, followed by the Summary of this Course option. From there, you can either download it or preview it in your SkyPrep platform.
The total time spent in a course will be displayed in the Total Time Spent In Minutes column of the report — just make sure you are in the Data tab and not the Summary tab of the report.
