Perhaps you should try some spelling variations:
duale studium » duales studium, dualen studium, das studium
le literatura » la literatura, de literatura, de litteratura
e literatura » de literatura, y literatura, e literatur
tests duale » tests due, tests scale, tests damage
a filosofia » la filosofia, e filosofia, di filosofia
studium a » studium am, studium ad, studium _

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tests duale studium a filosofia ((le literatura) OR (e literatura))*.
