This is a sandbox project, which contains experimental code for developer use only.
This module takes code from: http://drupal.org/sandbox/theunraveler/1187026 to add quiz functionality to the Webform module.
Users can add correct answers to webform questions, specify what percentage of answers must be correct to pass the quiz, and get a table of results with a percentage of correct answers.
This is a minimal effort for integrating quizzes, form builder, and webforms but rests on a solid foundation. Anyone who wants to build off of this please do so and we can change this into a full project.
