How to hide a course from the course catalog
If you're working on creating a course, but don't want students to see it mid-process, you can always hide the course from your organization's catalog so only you and other Course Team members can access it. Here's how.
From Open edX Studio, navigate to Advanced Settings - found under the Settings drop down menu.
Scroll down to the section called "Course Visibility in Catalog"
Change "both" to "none" and save your changes.
If you want the course to be seen in your catalog, but only allow viewers to access the About page, you can change this section to "about" instead.
