British Mathematical Olympiad

Welcome to the British Mathematical Olympiad

(22 July 2020)

The inaugural Cyberspace Mathematical Competition was held on 13th and 14th July 2020. This invitational online contest was organised by the Mathematical Association of America and the Art of Problem Solving. The UK team of eight students in Years 11 and 12 was chosen based on the results of the virtual selection tests in April.

The problems of the contest can be found here.

The UK team placed 11th out of 75 participating countries and our students achieved the following excellent individual results (out of the maximum 56 marks):

Wilf Ashworth34Bronze Medal
Thomas Frith33Bronze Medal
Mohit Hulse37Silver Medal
Samuel Liew38Silver Medal
Yuka Machino39Silver Medal
Jenni Voon25Bronze Medal
Tommy Walker Mackay38Silver Medal
Sherman Yip35Silver Medal

Congratulations to all students involved for some impressive solutions to the problems of this contest, and thanks to Dr Vesna Kadelburg for leading the UK team’s participation, and to the co-leaders Emily Beatty, Joe Benton, Robin Bhattacharyya, Kasia Warburton and Dr Dominic Yeo who assisted with marking.

The 2020 edition of the annual residential olympiad camp, due to be hosted at Trinity College, Cambridge, was cancelled because of the UK’s Coronavirus lockdown. In its place, BMOS organised a virtual camp, held April 6th to April 9th, for the twenty-six invited students, with lectures and problem-solving sessions delivered via video-conferencing software by a team of twelve volunteers. Following this, two rounds of selection tests were conducted online during the weekends of 25th April and 30th May. Based on these results, the students to represent UK at IMO 2020 are:

Samuel LiewThe West Bridgford School
Yuka MachinoMillfield School
Benedict Randall ShawWestminster School
Aron ThomasDame Alice Owen’s School
Tommy Walker MackayStretford Grammar School
Sherman YipTonbridge School

The reserves are:

Thomas Frith (first reserve)Horsforth School / Abbey Park High School
Sarah GleghornSkipton Girls’ High School
Sarah HendersonHighgate School
Mohit HulseSri Kumaran Public School

Congratulations to all students who qualified for these final rounds, and thanks to their parents and guardians for supporting the exams, and to our team of volunteers for setting and marking the papers, and leading discussions with the students. Thanks also are due to Oxford Asset Management for their support of the UK IMO programme in 2019–2020.

IMO 2020, originally planned for St. Petersburg, will now be hosted by Russia in an online format. The two papers will be sat on September 21st and 22nd. BMOS hopes that it will be possible for the UK team and their leaders to be together in one venue for IMO 2020, and we will offer updates and further details when the possibilities are more clear.

The Cambridge IMO camp, scheduled for 31 March to 5 April, has been cancelled, as a result of the ongoing COVID-19 situation. Obviously this is a great shame for the invited students and the volunteer staff. Our thoughts are also with all students, volunteers and their families who might be facing challenges or uncertainty this week and over the coming period. BMO will be in touch with affected students as and when it becomes more clear what form IMO programme activities can reasonably take for the rest of this academic year.

(11 March 2020)

The UK IMO training and selection camp is scheduled to be held at Trinity College, Cambridge, 31 March–5 April. The UKMT is keeping the situation and government advice under continuous review, and liaising with Trinity College. We will update students and parents as soon as possible if changes to the camp become necessary. We are working on contingency plans for some of the camp programme, including selection tests, to be delivered remotely.
