Question: I live in ireland,im fifteen,i really wanna learn more german so how can i exchange with german pupil cos there is alot of spanish students who come to our school for like a month or so? Help
Answer: Ask at the school or local education authority (via the school). I did some exhange trips with German students and actually ended up living in Germany!
See if your town/city is partnered with any foreign towns and they will have exchange programs.
Good luck.
Others:
Exchanges are usually arranged by your school. You should ask your German teacher.
