The school has already given us a schedule for what we can do. We’re going to museums, factory tours, that sort. So no suggestions for any activities to do or places to go to.
I would like some tips on some things I should know about Germany, perhaps some German phrases I should understand, cultural differences, or laws I need to know. Anything important that I should be aware of?
It will be about a weeklong trip


Once you get there, skip you teacher surveillance asap and go ask for political asylum? ;)
More seriously:
Not knowing you, it’s a bit difficult to suggest anything. I mean, I doubt you’re concerned but I’ve witnessed US citizens (I fancy your from the US?) complain that people in France (my country) were speaking… French, like for real. So, be aware that Germans will most likely speak their native German. And, yep, a lot of them do speak English, like us French do, just don’t expect all of them do.
Some EU citizens, from Germany too, are getting quite tired of US accelerated devolution into a dumbified mob-ruled country. Your POTUS insistence on insulting and threatening almost every single EU nation is also not helping much. So don’t be surprised some people may not be that welcoming to begin with. Edit: take that as an opportunity to show then they’re wrong.
If it’s a week long trip, don’t allow your school to say all you should and should not do in Munich (see? I did not suggest anything you should visit) ;)
Not from the U.S., no. I grew up in Hong Kong under an Asian household!
My bad!
Then, you mostly need to be aware that Germans are quite often on the reserved side of things, on first sight at least…
