Sorry for the Danish post i hope you can translate it.
The Ministry warns that Microsoft programs can create problems for written exams for students with Mac computers.
Users who have updated the programs to the latest version may experience the programs running slowly, freezing and crashing. This means that the examinees are delayed in their work and that parts of the answers risk being lost, write the Agency for Education and Quality and the Agency for IT and Learning in a notice to schools.
Yeah I assumed they would be centrally managed, but they are not apparently. So then I don’t really see why they would get a time extension to be honest. You could easily game that then and just fake it crashing.
