Cancel function

Hi,

Is there a "cancel quiz" -function for quiz takers?

This is how I see it could work:

1. User starts a quiz
2. User has answered 5 out of 10 questions
3. User decides to cancel the test and clicks "cancel test" -button under the answer options.
4. User is taken back to Quiz information page
5. a record with a note "test aborted by user" has been saved to user results...
