There are two perspectives for the progress calculation, which are overall course progress and progress through available activities.
The Academy dashboard has a progress bar for each course, which reflects overall progress. An example is shown from the Cyber Security Analyst course.
Inside the course, there is a completion progress tracker on the side, which shows a different percentage.
In this case, 86% of the unlocked activities have been completed, but there is at least one module that is still hidden because the overall progress is only 58%. The values will only be the same if all activities are unlocked.
Activities may be hidden and unlock via a schedule on predetermined dates or unlock when passing grades are received on assignments and quizzes. Once all the grade and schedule conditions are met, the next module will show in the completion progress tracker.
