Perhaps you should try some spelling variations:
duale studium » duales studium, dualen studium, das studium
le literatura » la literatura, e literatura, de litteratura
de literatura » de litterature, la literatura, y literatura
tests duale » tests due, tests scale, tests damage
3 filosofia » e filosofia, a filosofia, y filosofia
studium 3 » studium _, studium 1, studium 8

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: "tests duale studium 3 filosofia ((le literatura) OR (de literatura))*".
