Trouble is, you can't stop Admins from going anywhere, doing anything, it is inherent in the Role. Best option, change the Role. Create Categories with the Respective courses in them. Assign standard User Role to all Admins except those you want as Site Admins. Create your Admin Roles, if you want, but I am not sure it is actually necessary. Assign those Roles at the Category Level, not the site level. That way, the context of that Admin Role is at the Category level, not the site. That should do the trick.
