Perhaps you should try some spelling variations:
duale studien » duale studium, scale studien, duales studium
filologia la » biologia la, filosofia la, filologia slava
filologia e » filologica e, fisiologia e, filologici e
test duale » test double, test delle, test orale

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "test duale studien _ ((filologia la) OR (filologia e)) literatura".
• Adding a wildcard symbol may retrieve word variants: test duale studien _ ((filologia la) OR (filologia e)) literatura*.
