We have our homework assignments in Canvas set up as quizzes. We are concerned that some students might answer all the questions on the quiz but forgot to hit the "Submit" button by the time of the quiz deadline. In our old LMS, if this happened, we had to manually go in and submit the quiz for the student in order for it to be graded. In Canvas, we're not sure how this works. Does the system automatically submit all assignments (by the deadline) that have been opened and started by students, if the students themselves did not submit on their own? If not, are those assignments accessible to us in any way for grading purposes? We don't want a situation where a student gets a 0 simply for failing to hit the "Submit" button, and I'm worrying this might happen.
