Cultural Tip
German speakers often pair "vorbereiten" with the preposition "auf" and the accusative case ("auf die Prüfung"). In informal speech you may hear "Auf was muss ich mich vorbereiten?" – the meaning is the same, but "Worauf" is the more standard written form. Also, remember that the reflexive pronoun always matches the subject, so "ich" → "mich", "du" → "dich", etc.
