French Language level for studies
Most universities in France, specially the public ones, require the B2 (intermediate) certificate in the "Diplôme d'Etudes en Langue Française - DELF" or the TCF-DAP for international students. Few of them require the C1 (advanced) certificate in the "Diplôme Approfondi de Langue Française - DALF). The diplomas can be used for admission in French universities and are valid for life.
The Alliance Française of Dubai or Abu Dabi offer DELF-DALF preparation courses. You can find information on their website related to registration, fees and the exam's dates.
