If the course team determines that a submitted response is inappropriate, they have the authority to cancel it and remove it from peer grading. In the open response assessment, you will see an indicator showing that your submission was canceled, along with the date and time of the cancellation and a comment from the course team explaining the reason.
Depending on the course team's decision, you may or may not be allowed to submit a replacement response. If a replacement is not permitted, the assignment will receive a grade of zero.
