Following MDL-70895, default settings configured by admin from admin/settings.php?section=qtypesettingmultichoice can be changed by a teacher when they change the settings in their own course - Moodle remembers the teacher's choice.

An explanatory sentence for this is displayed on the page admin/settings.php?section=qdefaultsetting. It states "These defaults are used when a user first previews a question in the question bank. Once a user has previewed a question, their personal preferences are stored as user preferences."

However if an admin goes directly to admin/settings.php?section=qtypesettingmultichoice , they will not see this text and may not understand why their defaults are not being preserved in courses.

This ticket is to suggest that similar text is also displayed on admin/settings.php?section=qtypesettingmultichoice
