Please note that the Elentra Quizzes module is no longer supported. Use the Exams module to create quizzes.
A quiz created through the Elentra Quizzes module questions can be automatically graded, however a user must still import those automatically calculated grades into the course gradebook.
Navigate to Admin > Manage Courses.
Search for a course as needed.
Click the cog icon to the right of the course name and select Gradebook.
Ensure you are in the correct curriculum period and adjust using the period selector in the top right if needed. (The current curriculum period will display by default.)
Click an assessment name.
Click the Import/Export button and select Import grades from attached quiz.
Indicate how you'd like to apply grades (e.g. first attempt, best attempt).
