Besides guessing the medals, I think it's also interesting to guess the regional champions.
My bets are:
European champion: SPbSU
Asian champion: Tsinghua U
North American Champion: University of Waterloo
South Pacific Champion: University of New South Wales
Latin American Champion: Universidad Nacional de Córdoba
Africa and Middle East Champion: Faculty of Computer and Information Sciences, Ain Shams University
And I'm also guessing that I wrote them according to their relative order in the scoreboard.
