I use New Quizzes for weekly brief student submissions. Due to a large number of students, I have the quiz setup to autograde using Multiple Choice questions. However, I also include ungraded essay questions (worth 0 points) so students can add some extra relevant details to their submission. However, even though the 'essay' question is ungraded, I am still required to grade each student before their grade is released.
I would like for the ungraded essay questions to not prevent the quiz from being autograded. An alternative is to make a new question category that is not an essay but allows a student to type their feedback within the quiz/reflection.
