I'm really struggling with the new quiz tool, mainly the auto-grader.

I have a type of quiz that is 4 essay questions, which means that I have to go in and grade them before they get any points. The problem here is that the auto-grader adds the quizzes as zeros immediately when the students complete the quiz. This creates two problems:

1) The students' grades go down until I can complete the grading, and

2) I can't tell the difference between a quiz I gave a zero because it's missing and a quiz that hasn't been graded. This makes me worry that I will miss grading late quizzes or retakes.

Is there any possible way to change this setting so that it stops auto-grading these quizzes?
