Did you follow all the steps in the Interactive Video Quiz Canvas Gradebook Integration Deployment Guide to deploy the graded quiz?
If so, did you set a Points value for the Canvas Assignment when you set it up?
If you did not set the Points value in the Canvas Assignment screen, the value in the Canvas gradebook after submitting a quiz assignment will be 0. You will still see students’ responses and scores in Kaltura analytics for that quiz.
To learn how to access the Kaltura analytics page for a Quiz, see the “Quiz Reporting” section in the Interactive Video Quizzes Guide for Creating Quizzes.
