In DO180 course material Orientation to the Classroom Environment it says, "Students are assigned remote computers in a Red Hat Online Learning classroom. They are accessed through a web application hosted at rol.redhat.com. Students should log in to this site using their Red Hat Customer Portal user credentials."
I don't see any "web application", just the My Progress section and the options at the top for REDHAT.com, Support, and FAQ and the Home and Community tabs.
I'm trying to get to the workstation.
