QuizMeister provides social network share functionality for your quiz score (via Twitter, Facebook, etc.) with external media support (via Imgur, Pintrest, YouTube, Vimeo, etc.) on quiz questions, through oEmbed. The format is multiple questions, each with multiple answers. This brings additional value to your WordPress blog or website, which can synergise with your existing content.
For external/social login support (Google, Facebook, etc) we suggest installing another plugin such as WP-OAuth. This functionality -may- be incorporated into later versions. The included template integrated into the plugin for displaying quizzes (but with the ability to be disabled) is most compatible with TwentyFifteen (included with WordPress), but there is the possibility of creating your own overriding template.
Future versions will include bugfixes and feature enhancements.
