I'm trying to drum up support for a new 7.x-5.x branch of the Quiz module, optimized for Drupal 7 (not a straight port from Drupal 4/5/6) so that we can more easily port it to Drupal 8 in the future without the technical debt that Quiz currently has.
I created a Github project with a lot of refactoring work already to effectively use the Form API, Entity API, Views, Rules, Menu system, to replace the existing one-function engine currently in 4.7-1.x through 8.x-4.x. I'll move it to Drupal.org once it's moderately stable again. I used Github so I could fork the main module code.
Here's the Drupal sandbox project which has a lot more information about the issues: https://drupal.org/sandbox/devin/1287518
If you use Quiz in your LMS I'd love to hear your thoughts about this.
