" After I had decided to study French and German at university I started doing research into various institutions. Swansea appeared high in the league tables for both French and German, and after applying was the only university to invite me to an interview. It was only after seeing the campus and personally meeting the academic staff that my decision was made to study in Swansea, and I have not looked back. From the academic tuition through the first and second years to the guidance and support offered during the whole year abroad process, Swansea has treated me like an individual. Every year in both departments there are modules offered which interest, stimulate and challenge students, such as European history modules and literature from various time periods, which interested me. The year abroad gave me the opportunity to experience the atmosphere and culture of a completely different country; it was an unforgettable experience and I would thoroughly recommend it. During my studies, I have come to love Swansea not only as a university but as a city, which is why I decided to stay on to do postgraduate studies in German. "
