Hi, I saw you posted this link regarding RHDE quick course series.

Familiarity with RHEL system administration, to the level of RHCA (Red Hat Certified System Administrator) or equivalent knowledge.

I noticed that typo on the introduction page, not sure who to report it to. That should be RHCSA not RHCA (RHCA is Architect level)

I see the error at https://role.rhu.redhat.com/rol-rhu/app/courses/hol014-9.5/pages/pr01 we need to push a new HOL014 book build with the fix
