Quiz Archiver

Archives quiz attempts as PDF and HTML files fully automated and asynchronously for long-term storage independent of Moodle. Backups of both the quiz and the whole course can optionally be included.
Quiz Archiver
Archives quiz attempts as PDF and HTML files for long-term storage independent of Moodle. If desired, Moodle backups ( .mbz ) of both the quiz and the whole course can be included. A checksum is calculated for every file within the archive, as well as the archive itself, to allow verification of file integrity. Archives can optionally be cryptographically signed by a trusted authority using the  Time-Stamp Protocol (TSP) . Comprehensive archive settings allow selecting what should be included in the generated reports on a fine-granular level (e.g., exclude example solutions, include answer history, …).
Generated quiz attempt reports include all elements of the test, even complex ones like  MathJax  formulas,  STACK  plots,  GeoGebra  applets, and other question / content types that require JavaScript processing. All PDF and HTML files are fully text-searchable, including rendered MathJax formulas. Content is saved vector based, whenever possible, to allow high-quality printing and zooming while keeping the file size down.
Quiz archives are created by an external  quiz archive worker  service to remove load from Moodle and to eliminate the need to install a large number of software dependencies on the webserver. It can easily be  deployed using Docker . If you want to try the Quiz Archiver without setting up your own quiz archive service worker, you can also use the free public demo worker .
