Perhaps you should try some spelling variations:
duale studium » duales studium, dualen studium, das studium
da literature » da literatura, la literature, ca literature
dd filosofia » di filosofia, de filosofia, da filosofia
test duale » test double, test delle, test orale
studium dd » studium ad, studium d, studium der

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 studium dd filosofia ((da literature) OR (a literature))*".
