These steps require that you have completion tracking enabled in your course.
A common activity in Moodle is to have students earns a specific score on a quiz. You can set up Activity Completion to mark a quiz as complete if the student earns a passing grade.
This is ideal for warm-up quizzes and terminology tests, where you want to encourage students to take a quiz/test until they pass it.
