How do I view a list of my earned certificates?

1. Login to the classroom
2. Click on your name in the top right
3. On the right side of your profile, click "Activity Reports" then "Certificates Issued"

FYI, the default behavior of courses is now to hide the certificate of completion link IF you haven't earned it yet. So, if you don't see the link to view a certificate you should be able to safely take the course.
