The Output panel displays the following text:
You got 11 out of 13 answers correct, for a score of 84.62%.
When you call Math.round() in this example, the score rounds to the nearest integer (85)
and is displayed in the Output panel. If you multiply the number by an additional 100,

the SWF file again.

multiple choice questions using the RadioButton and Label components. After users finish

to an answer key and then calculate their score.
