Below from Live Scoreboard. Notice all 4 members from China team have Gold ranking in the live scoreboard, but in the final results, China team won 2 Gold and 1 Silver.

I am inclined to believe the China team did not cheat. But they should not have brought mobile phones into the contest area.

Singapore IOI Team Members' University Destinations

I wrote a post on Singapore IMO Team Members' University Destinations here.

Below are the university (undergraduate and postgraduate) destinations of the Singapore IOI team members in the last decade. Top 3 university choices are NUS, MIT and Cambridge. Note that most of the guys have had to serve 2 years of compulsory National Service (NS) after their High School, before joining the University. Those guys and girls with no NS obligation are marked with #.
