Limit Attempts settings has no effect on courses for students

I have set up a course that should allow users to answer questions 3 times - however there is no method to allow this or to allow the whole course to be retaken.

In my opinion it would be better anyway if the user could be allowed a set number of attempts to redo the course - rather than this setting that relates to each individual element.

On my demo I would like to allow a student to take the course up to a set number of times. Or allow the instructor to reset the course for the student to retake.
