All the very best to your daughter ... and make sure she keeps her languages going! It might be worth trying to supplement her language qualifications outside the Baccalauréat by taking the Cambridge series of examinations (First, Advanced and Proficiency) to boost her English and the Goëthe-Institut series - ZDaF (Zertifikat Deutsch aus Fremdsprache) or ZMP (Zertifikat Mittelstufenprufung) ... your local Chamber of Commerce and Industry (CCI) may have a languages centre as we have in Colmar.
