If there is no response immediately, please try to be patient for a few minutes. If you want to back out and try again, hit the Stop botton on the tool bar; please don't press the TURN IN button again until you've done this.
If there are errors, you'll be told, and you can turn-in again. You can turn in as many times as you wish; only the last turn-in will be graded. Previous turn-ins are not graded.
