IB Biology and History SL papers in GERMAN?

I urgently need to get hold of past papers for IB (international Baccalaureate) Biology and History Standard Level but NOT in English, I need them in German. I`m tutoring a Peruvian student who goes to a German school in Peru and so they do these two subjects in German for the IB, but I can`t for the life of me find past papers in these subjects in any other language but English. Thank you so much
