If you create a quiz, then 'add a new question' rather than add 'from question bank' (in the Quiz administration > Edit quiz screen), you may stumble into this problem. If you leave the Category as 'Default for [topic name]' or choose another category that you have already created, there won't be a problem. But if you choose the category ‘Default for [quiz name]’ from the pull-down menu, the questions will belong to the quiz and you won't be able to see or use them for any another quiz in the topic (eg in a revision quiz, or an end-of-topic exam that draws from questions used in formative quizzes throughout the topic).
Solution to prevent this problem
Do one of the following:
Go to Question bank from your topic homepage (Administration > Question bank). Create a category and questions first, before you create the quiz, then add questions into your quiz 'from question bank'
Create a category, then create the quiz and 'add a new question', making sure the new question goes under the category you have created
If you already have this problem and need to use your questions in other quizzes:
From your topic home page, go to Question bank > Categories
Create a new category (probably best to make the parent category 'top')
Go to your existing quiz, then Administration > Question bank
Select all questions which are in the quiz's default category, then using the 'With selected' menu at the bottom of the page, move to your new category
Note: Questions can be moved to different categories even if they are already used in quizzes, though be careful if they are used as random questions in a quiz.
I can't unhide the grade column for a quiz
Quiz results visibility settings are controlled within the settings of the quiz activity, not in the gradebook.
Please see the entry Create a quiz – scroll down to Review options for further information.
I can't add/delete questions in my quiz
Once a quiz has been attempted, no additional questions may be added to that quiz, and no questions can be deleted (removed).
The following message will display, and the Add to quiz or Delete button will appear greyed out.
You can however delete questions if no attempts have been made. To delete multiple questions:
Click Select multiple items button
Click Select all or select individual questions
Click Delete selected
You will be asked to confirm deletions, check these are the questions you want deleted
I have assigned answers to a quiz question incorrectly
If, before a quiz opens, you discover that a question requires editing or correction, it can be easily edited. Enter the Question bank and locate the relevant question, then select the edit cog besides it. After making the required changes, click Save changes.
If you discover the error after student access has commenced, it is possible to regrade your quiz. To regrade a quiz attempt you will first need to edit the quiz question that needs changing. When a quiz question is altered all instances of that question will be altered (eg if the question is used in another quiz it will also be altered). Students will not be notified of the changes made.
I accidentally deleted a quiz and want to restore it
What you should do
If you accidentally delete a quiz and want to restore it you can either:
recreate the quiz – deleting the quiz activity does not delete the questions from the question bank (the original questions are available to use)
contact your local eLearning support team to discuss if it's possible to restore the quiz from a previous availability.
What you should not do
You may be aware that you can restore deleted activities from the recycle bin, however, this is not recommended for quizzes. Restoring a quiz from the recycle bin will duplicate the question bank (make a copy of each question). If quizzes in your topic use random questions, students may receive the same question more than once. If you've restored a quiz from the recycle bin you will need to delete the duplicate questions before any quiz with random questions opens. Duplicate questions have '(copy)' appended to the question name.
