As far as I know it is sort of an interview where they ask scenarios about you flying as pilot in command responding to ATC or a ground operations handler. For example "Say you are on approach to land and the tower says there has been an accident on the runway 12 and ATC asked you to go around. What would be your response?" ..........Ans. N123AB in the missed approach. Remember they only want to see if you understand the language.
Good luck with the exam it is fairly easy
