English courses for au pairs who plan to take the Cambridge Exam

[goocha]

Hi,

We have an au pair from Germany with excellent English and we are trying to find an English class to suit her level of English. She plans to take the Cambridge English Exam at the end of her year here.

She tried going to South Thames College but found it too easy. Our previous au pair found Lambeth College too easy as well.

If anyone knows of more challenging English language courses or schools please could they let me know.

Thanks.

I understand you, it?s hard for me to study either.
