Grade Center columns can be shown or hidden as appropriate for your course. You may also find that some columns are hidden if you are working from a course that was set up by another instructor. To update what is hidden in your grade book, follow these steps:
1. Navigate to Full Grade Center, then select Manage > Column Organization in the top menu.
2. In the Column view, scroll down and you should see the hidden quizzes in the list. You can select them as needed, then select the Show/Hide button near the top of the list.
3. You can use the cross shaped emblem to the left of the checkbox to drag and change the order of items in the list. This will also change the order on the main grade book screen.
