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.
Fair enough, but if it was at work or something you can at least say, ‘eh at least I still get paid’ Here you have no recourse options.
edit: Having read the translation now. It seems the students do have a choice in which software suite they use. So I guess they did have a recourse. So in the end it was their own responsibility. I guess it was a good lesson then.
I can’t speak for every University, but some have a way for you to appeal issues like this to the Dean.
