Halls - is Birchen mainly for returners?

Hey
I just got my accommodation allocation - yay!

I am in birchen. But I was looking up stuff about it and it seems to be a hall mainly for students returning to halls in second year.

Is this true?
If it is, will they try and group first years in to one flat and second years in another, or will it be mixed?

I'm just a bit anxious that I will be in a flat with a lot of returners who have already made friends

Thanks!

Hi!
I'm a first year and I've been allocated accommodation in Birchen too - apartment A2. I was wondering the same thing, at least we know there will be 2 of us!
What are you studying?
