Faculty Question of the Week (February 26, 2026)

February 26, 2026

Each week we'll use this space to share a question (or more!) that we've received about Quercus and other Academic Toolbox tools. 

This week's question is: Is it possible to bulk-adjust grades in a Quercus quiz for students who have already submitted it, if a question is corrected after their submissions?

Q: There is a multi-choice quiz question currently open in my Quercus course that has an error, and I would like to update it. Some students have already completed the quiz.

If I update the quiz now, will the corrected question apply to students who take the quiz from that point onward? For students who have already completed the quiz and were affected by the incorrect question, is there an automated way to bulk adjust their grades, or will I need to manually update their marks for this question in SpeedGrader?

A: Yes, if you update the quiz now, the changes will apply to students who have not yet taken the quiz. These changes are not applied retroactively. However, students who have already taken the quiz and might be affected by an incorrect question can have their marks bulk updated using the Quercus regrade option.

Regrade a Quercus Quiz Question

The quiz regrade feature can be used when a quiz has already been published and students have submitted responses, but a correction is required.

Please note that quiz regrade only works with specific quiz question types and only applies to students who have already taken the quiz. For detailed steps on how to regrade a specific type of quiz question, see the following guides:

Regrade Restrictions

Quiz regrade does not apply to questions linked to a question bank, as these questions may be used in multiple quizzes. Adding or deleting answers from a question with existing submissions will also disable the regrade option.

If these situations apply and the regrade option does not appear to you, the grades for affected students will need to be manually adjusted.
