Handling of cases where exercises with 0 minutes (or empty minutes fields) are used, or when the full exam has no minutes specifed
- Provide a hint on lecturers dashboard for questions with 0 minutes - Don't provide timer on the lecturers dashboard - Don't provide timer for the students - Don't show timer for very short exams/quizzes (below 1 minute) - Provide a hint on lecturers dashboard when no timer is displayed - When the countdown timer has expired more than a minute, display the text that the timer has expired, rather than counting to negative values.
Hints: * It is recommended to set the end-time of the exam manually, when a time window is specified and the total exam time is provided as 0. * When there is no timer, the special autosaving semantics for the end of the exam will not work (trying to get a snapshort short before the exam end). * When there is no time-budget, the time budget control ("be able" exams) won't work
fix potential loss of statistics for autograded exams
when filtering by form objects (i.e. single question) omit the grading table and therefore as well overwriting of the statistics with partial values. Previously, only the values of the show questions were displayed, until the full exam protocol was rendered again
