From your Admin Dashboard, click on Online Training.

There are two ways you can modify settings: Globally and on an individual course level.
Click the Settings tab at the top of the Courses list to change settings globally, or navigate to the course of your choice and click the Settings tab at the top.
Now if you are wanting to change the settings for an individual course you'll see that by default the global settings are applied:
​

Global Settings

Course Settings

You will need to uncheck the default global setting to modify the settings within a course. This allows you to make specific changes to individual courses without the global setting automatically applying. Please note that if a course has the global setting option unchecked, any changes made to the global setting will not affect that specific course. The global setting will only apply to courses where it is checked.

If you need to modify the setting for a specific course, go to the Online Training component, select the desired course, and navigate to the settings tab. There, you can customize the settings according to your requirements and save the changes.
