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.
While I agree with you that LaTeX is an impressive tool, I would not choose it for an exam whith a short duration. It is great, but for short documents that should be written quickly, I don’t think it’s the best tool.
I (almost) only use LaTeX now, I find it easier than having to manually set headings etc. I find it great even for just one page notes.
The few times I do not use it is when I have to colab on a document with someone else.
I’ve used it a lot for reports when I went to university, but for short notes I would prefer markdown and for a few pages or documents where formatting is trivial I still find it easier to use LibreOffice or word. I find it likely that most high schoolers would find it easier to use word for any document than LaTeX which they probably have never heard of and would be unable to get support for unlike word which is commonly provided by the school. So while understand where you are coming from, I don’t think the students are in a situation where that would be a plausible solution. Especially due to the many pitfalls and the learning curve you have to get through for using LaTeX as efficiently and for as complex formatting as they already know how to do in word. LaTeX has a way higher ceiling of quality, but the floor is also much lower for those new to it and without the drive to learn it.
