The OIB adds further subjects to the French national exam. Students choose one of the L, ES or S streams. It differs, as students take a two-year syllabus in literature, history, and geography in a foreign language. That syllabus and the way that it is examined is modelled on the national exam of the target nation. For instance, the British Section (administered by the University of Cambridge) models the programmes on A-levels in English, History, and Geography. It is therefore necessary to be fully bilingual to complete this qualification. To date there are 15 different sections supporting 14 different languages, thus: American, Arabic, British, (mainland) Chinese, Danish, Dutch, German, Italian, Japanese, Norwegian, Polish, Portuguese, Russian, Spanish and Swedish.
