As a German I would say test that they actually keep up with all their duties. I feel like for many years ours do a terrible job, but at least they don’t try to overthrow the government or anything. So… test that they know and are willing to perform their duties:

The president’s most prominent powers and duties include:

• Proposing the chancellor to the Bundestag
• Appointing and dismissing the chancellor and their cabinet ministers
• Dissolving the Bundestag under certain circumstances
• Declaring the legislative state of emergency under certain circumstances
• Convening the Bundestag
• Signing and promulgating laws or vetoing them under certain circumstances
• Appointing and dismissing federal judges, federal civil servants, and commissioned and non-commissioned officers of the Armed Forces
• Exercising the power to pardon individual offenders on behalf of the Federation
• Awarding honors on behalf of the Federation
• Representing Germany at home and abroad

Currently, German presidency is a deportation track for political pensioners.

what country if I may ask?

I hated languages in school because besides grammar and word mistakes, grading always felt arbitrary. However, that teacher recognized that I struggled, gave me a generalized template and said “If you do it like that, you get a good grade”. I did it like that and got a good grade (we have 1 (perfect) - 6 (trash) and I improved from 4- to 2+ which is quite a big leap). So yea, that was the first time that I perceived that subject and a teacher of that subject as something real and not bs.

It’s not a grammar mistake per se, but I feel like sharing it and it is close enough so here we go.

As a non-native English speaker: How can you have mob and vacuum the floor but not broom the room?! I know it doesn’t exist, but I don’t care. If we have to phrase it as a grammar mistake: I use verbalisations where they are uncommon.

I have set up a good hand full of dual booted Windows/ Linux machines. Never had any major issues. However, I also noticed that I only use Linux except for games and that’s slowly changing, too, so I would suggest trying the dual boot if it makes you more comfortable to realize yourself that you don’t need it.
