Go to Your Name (top right) > Notifications
Once in notifications, select what notifications you want to receive and the method you would like to receive them
Scroll down to “Exclude some courses” and click on “Manage my course exclusions“
A window will pop up with a list of your courses, you can exclude all the courses you do not want to get notifications from by clicking on the x next to the course.
