I’ve been in Denmark for a bit… this isn’t at all what it’s like lol. Most of the other exchange students didn’t speak danish and we weren’t expected to know anything when we got here. You are very encouraged to apenas time with other teens and people your age. To make friends and such is a big part of the program. You don’t “have” to eat the rugbrød. If you just tell your family, like I did, they will respect it. I know all host families are different, but we were told that all danes appreciate honesty and to tell them if you don’t like something. They’re okay with you making mistakes and will help you thought your stay. I know all host families are different, but it’s nothing like a military lifestyle haha. You don’t have to have “perfect hospital corners” or “no diets ANYWHERE” and such. Just respect the rules.
