We had scheduled a quiz activity in Moodle. While student were answering quiz suddenly power went off and it was restored after 10 minutes. When all students re-logged in to Moodle to continue their test, their leftover time was reduced by 10 min. My doubt is is there is any way/configuration in moodle to pause timer on moodle server in event of client crash. Help in this regard is appreciated.
Not possible. From the Moodle server's point of view, it is impossible to tell the difference between the student suffering a 10-minute power cut, and the student logging out of Moodle for 10 minutes in order to go an search Google for answers to the quiz.
