It has been a while since quiz module was actively developed and maintained. But I'm sure that this period of 'while will not find its repetition in future.
With the support from my company, "KnackForge" and for the healthy growth of the quiz module we have strategically relaunched our existing service which would specially focus on offering Drupal development services based on quiz and related eLearning modules.
We hope this will please the users' requirement & at the same time could make way for the further development and maintenance of the quiz module. To know more about it, check out http://knackforge.com/service/professional-support-quiz
As a showcase for this service we have managed to contribute a few question type modules to the community & a few more yet to be released in the coming days.
We are excited to work with community & in favor of its ecosystem.
