By default, students can take courses as often as they’d like. However, the time spent on each course will not be tracked after successfully completing it.
You are able to, however, set up your academy so that the time spent on each course is tracked each time it is taken. The time spent on each subsequent retake will be recorded separately.
To set up this functionality, in your Admin tab, under Your Academy in the right menu bar, click Academy Settings.
Then, under Advanced Settings, scroll down and click Reporting.
Click the toggle switch next to Time after first course completion counts, and save.
