Hello,
You won't ever see the score report again, so it's good that you've written it down. When you close the program, it will ask a few questions:
1. Are you sure you want to end your exam? -- Choose Yes.
2. You have chosen to end your exam. Do you want to leave this session unfinished? -- Choose YES.
(If you choose NO here, the exam will be marked as COMPLETE).
When you enter back into the program later on, it will either say that the test is Unfinished or Complete (depending on what you chose before).
If it says Unfinished, when you click on it, it will prompt you with "Do you want to continue from where you left off?"
If you select YES, it will return you to the Review screen.
If you select NO, it will discard all your answers and should let you retake the exam.
If it says Complete, when you click on it, it will start over from the beginning and allow you to retake the exam.
Note: Remember when you select it, you have to check the exam and then select OK at the bottom.
Hope this helps!
