The University Language Service ( SUL) welcomes exchange students of various nationalities and supports them as they discover and/or improve their modern language skills. Multilingualism is a key focus of its work. Since 1953, the Pôle FLE, based in Aix-en-Provence, has been offering a wide range of courses in French as a foreign language at all levels of the CEFR. Carlam, based in Marseille, provides resources, self-study materials and language qualifications.
