For every activity in your course it is possible to specify when learners can interact with it.
🔏 You can do this is by specifying other activities that have to be completed first – we call these prerequisites.
The above screenshot is an example where the activity will only be open to learners when they have already completed the 'Submit your work' activity.
Where to set prerequisites
When you are looking at an activity as an instructor, click to edit it. When editing the activity, scroll to the bottom of the settings page to locate the box called "Prerequisites".
To specify prerequisites, select '+ Add prerequisite'. Now you can select which activity learners have to complete first before they can access the activity you're currently looking at.
