Scores can be assigned to question choices within your survey. For example, if you’re running a multiple choice quiz, you can assign a score of “0″ to the wrong answers, and a score of “1″ to the right answers.
Instant feedback can be provided to respondents through the Score Display question type. It will display the tallied score of all the questions on preceding pages.
When would this be useful?
Often times, you may want respondents to see their score as they move on through the survey. When you add in a score display question type, they’ll be able to see how they’re doing, in real time.
