sprachreise

Hi there! I like to study a language course which training is exclusive to junior [sprachreise](http://www.esl.ch/de/sprachaufenthalt.htm).
I like to know what commonly approved language courses are available
for young people. I prefer my son to study in a competitive environment where
all his classmates are his age, because some language course programs
cater to everybody and I don’t think it’s such a good idea. Thank you.
