Sometimes you may want to delete a student's responses in a formative to allow them to retake, instead of editing their responses. (If you'd rather allow them to unsubmit, edit and then resubmit, find out how to do that here!).
To remove a student's responses from a formative, click on their name in View Responses first, and this will bring up a side panel containing all of their responses to that formative. You can then click on the triple dots next to their score, and select the option to remove responses:
This will remove the student's responses from both View Responses and the Tracker (you may need to refresh the page). Note: this cannot be undone!
As long as the formative is still open, the student can log back in and retake the formative from scratch. When they do this, their new responses will be recorded in View Responses and the Tracker.
