its in german, however for the simulator test, you wont need to know german:
click on "Klicken Sie hier: Zum Pilotentest"
a new window will pop up, by clicking on "Test starten" you will get to the questions which are in german btw
however by clicking on "simulator" you will get to the simulator test, where you will have to keep the aircraft on track (no german needed )
also here is a video which belongs to this test, its about the flight training at Lufthansa (german only)
