China Girls Mathematical Olympiad problems (13 August 2010)

The China Girls Mathematical Olympiad problems are now available. Note that this is a draft version of the paper; in the final version, problem 6 was split into two parts, where the first part was to prove that F was on the circumcircle of ABC. This paper may be replaced by the final version when available.

China Girls Mathematical Olympiad results (13 August 2010)

The China Girls Mathematical Olympiad papers were sat on 10 and 11 August. The results of the UK team members are shown below (each question marked out of 15, with individual question scores always being multiples of 3). In addition to the medals shown, Alice collected first prize for the dance aerobics competition (Maithra was also in the dance). The medal boundaries were 72 for Gold, 54 for Silver and 33 for Bronze. The team leaves China today and arrives back in the UK on 14 August.

China Girls Mathematical Olympiad Paper 2 (11 August 2010)

The second paper in the China Girls Mathematical Olympiad in Shijiazhuang was sat today; the problems will appear here when available. Coordination of the UK scripts on both papers has been completed; the UK team received the following scores (each question marked out of 15, with individual question scores always being multiples of 3).

China Girls Mathematical Olympiad Paper 1 (10 August 2010)

The first paper in the China Girls Mathematical Olympiad in Shijiazhuang was sat today; the problems will appear here when available. Coordination of the UK scripts on this paper has been completed; the UK team received the following scores (each question marked out of 15, with individual question scores always being multiples of 3).

UK team members in other olympiads (10 August 2010, updated 11 August 2010)

Ruth Franklin, currently competing in the China Girls Mathematical Olympiad in Shijiazhuang and also a member of the UK team in the Balkan Mathematical Olympiad in 2009 (where she received a bronze medal), received a gold medal at the International Chemistry Olympiad in Tokyo. An interview with Ruth was broadcast by the BBC on the 5 live Breakfast show today and is available from iPlayer for the next week; the interview starts one hour, 27 minutes and 19 seconds into the programme. A longer interview with Ruth was broadcast on Beswick at Breakfast today on BBC Manchester and is also available from iPlayer for the next week; the interview starts 13 minutes and 13 seconds into the programme.

Sergei Patiakin, a gold medallist in this year’s IMO team and a silver medallist in the Balkan Mathematical Olympiad this year, received a gold medal at the International Physics Olympiad in Zagreb. Both this year’s IMO reserves also competed in the IPhO and received bronze medals, Andrew Hyer for the UK and Jordan Millar for Ireland. Andrew and Jordan have both represented the UK at the Balkan Mathematical Olympiad and Andrew has twice competed at the Romanian Master of Mathematics.

China Girls Mathematical Olympiad team in Shijiazhuang (9 August 2010)

The UK team for the China Girls Mathematical Olympiad arrived at the olympiad in Shijiazhuang yesterday after spending the previous week in Beijing. While in Beijing they have been preparing with practice exams, adjusting to the timezone and visiting local attractions including Zhongshan Park, Tiananmen Square, the Forbidden City and the Great Wall.

The olympiad, held at Shijiazhuang middle school no. 2, takes place from 8–13 August, with the opening ceremony today, the papers being sat on 10 and 11 August and the team returning to the UK on 14 August.

China Girls Mathematical Olympiad team training in Beijing (2 August 2010)

The UK team for the China Girls Mathematical Olympiad is spending this week in Beijing for final training and acclimatisation. The team members and accompanying adults coming from the UK have arrived in Beijing while one team member coming from elsewhere arrives tomorrow. The olympiad takes place in Shijiazhuang, capital of Hebei province, from 8–13 August, with the papers being sat on 10 and 11 August and the team returning to the UK on 14 August.

IMO 2010 report available (23 July 2010)

The reports on past IMOs now include Geoff Smith’s report on IMO 2010.

IMO 2010 results (11 July 2010)

The IMO papers were sat on 7 and 8 July. The results of the UK team members are shown below. We obtained one Gold, one Silver and two Bronze medals and two Honourable Mentions and a score of 114 out of 252, coming 25th out of 96 participating countries. The medal boundaries were for 27 for Gold, 21 for Silver and 15 for Bronze.
