While reviewing the ANU LMS module documentation, I noticed a mention of linear course progression, but I can't find this feature in the application.

The feature does exist. Thank you for bringing to our attention lack of documentation. The Anu LMS documentation might need a broader improvement, however to address this particular issue, I've added a mention about the linear progression feature in this section: https://www.drupal.org/docs/contributed-modules/anu-lms/create-courses-a... →

Good afternoon!

I apologize if I wasn’t clear earlier. Unfortunately, I haven’t yet managed to configure the linear progression between courses.

Based on the documentation, I was able to configure the following:

This part I managed to set up:
*Linear lesson progress (i.e., access to Lesson B is given when Lesson A is completed)
I was able to do this by activating the flag that makes the lessons dependent on each other for access.

This part I couldn’t set up:
*Linear course progress (i.e., access to Course B is given when Course A is fully completed)
I couldn’t find where to set it so that to access Course X, Course B must be completed first.

I’m considering creating a new reference field within the course to specify prerequisites. This way, I could define which items need to be completed to grant access to a specific course.

I plan to implement this solution, and if it works, I can suggest it as an improvement for the module.

I've discovered where to configure the course's linear progression! You need to access the course category in the taxonomy, select the desired term (preferably one used by multiple courses), click on 'Edit,' and go to the 'Sort courses' tab. There, you can arrange the course titles as you prefer and check the option 'Courses must be completed in this order.'

I apologize for any earlier confusion, and as a suggestion, I believe this discovery could be added to their documentation.
