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.
The article says that the Ministry has suggested students use other programs, so it sounds like it’s just something students often use rather than something that’s actually required. I’ve not been in school for a long time, but I am doing a distance learning course and when I had to submit some written stuff I definitely found it more comfortable to type it up in an actual word processor than the web platform that only showed about a paragraph at a time, so I did that and then copied it to the web platform.
Word specifically is not required, but electronic hand in is. If it works the same as when I studied at that level (I am a Dane) you simply hand in a pdf file, but how it is made doesn’t matter. A web interface to write in was never a thing throughout my education though.
