I'd maybe learn Giotto or Michelangelo just to be on the safe side. There's notes on Giotto around halfway down this page: http://artroom32.blogspot.ie/p/history-of-art-notes-2013.html Even if you just knew how to draw the Deposition and learn about his style and the composition, you'd probably be okay. It's hard to say, like you could very well be okay with just impressionism, it's very likely to come up but you never know.
Bronze age or newgrage for section one i'd say. for the third section just do the gallery, learn off an essay in detail and twist it to suit the question asked tomorrow. For the European, like Gothic is guaranteed but it's not a nice topic.. I'm hoping Giotto and Masaccio come up considering they were in the mocks. Impressionism is a maybe too.
