When does a learner complete a Quiz?

Hi Liu,

Thanks for reaching out!

A passing score is set for each result slide that you add to your course: 

If you're tracking your course completion using a quiz result, your learners will get a failed/incomplete mark in an LMS if they do not meet the passing score requirements for the course. Take note that this will also be dependent on which reporting settings you select when you publish your course.
