Answer 1

Try

cascade="all-delete-orphan"

Answer 2

Note that the "orphan" part doesn't have anything to do with cascading the deletion of a course to that of the tutorials, it allows

c.getTutorials().remove(tutorialToDelete);
session.merge( c );

to delete the tutorial that was removed in the collection instance, I don't know if there are performance issues associated with the orphan flag, but if you don't rely on that behavior you may just want to switch it to

cascade="delete"
