We’re sorry for this error and the inconvenience it brought . You’ve done the most important part already - contacting us.
Should this error happen again, please:
- close the browser window or tab.
Don’t retry submission immediately. This is because the grading process is most likely still running in the background and might cause the instance to freeze.
- start another course. This should reset your instance and stop the running grader.
- Go back to the course and retry the quiz again.
- contact us if you still cannot submit or your trial has been “wasted”.
I have checked and found that the grading process did not complete, so could you please try submitting it again?
