What do the students see when I publish the course?
Students will see all content that is marked as ‘Published’ (with the green checkmark) and any navigation items that have not been hidden.
Check the Student View to see exactly what your students see when you publish.
* NOTE: You’ll need to publish the course before it can be previewed in Student View.
See the Canvas Guide:
