Per the Canvas Guide, "If a quiz includes more than 65 total submissions, individual attempts cannot be viewed in SpeedGrader. To view prior quiz attempts for a specific student, click the See all quiz attempts link."
This essentially removes the drop down menu to see a students different attempts, making essay/short answer questions harder to grade.
If I have more assignments to grade (over 65) I need it easier, not harder, to grade. As it is, I have to click over to a new page to see all attempts for one student, but cannot then click a next button to go to the next student. So I click on go back to quiz, which takes me to the main quiz screen and then I have to click on speed grader, only to then have to leave speed grader to actually grade the assignment. This is very frustrating and time consuming.
