27+ (yr 13, S6, NI14), 26+ (yr 12, S5, NI13), 24+ (yr 11, S4, NI12 and below)
Stretching high-attaining young people
The British Mathematical Olympiad Round 1 is a follow-on round to the Senior Mathematical Challenge. As well as challenging high-scorers from the Senior Mathematical Challenge, the British Mathematical Olympiad is an entry point to the training and selection programme for international competitions.
Changes for 2020
This year, in reaction to Covid-19, we have made some changes to the paper to make it easier for schools to take part and for us to mark scripts. BMO1 2020 is a 2.5 hour Challenge consisting of 2 sections; section A has 4 'answer only' questions, with partial marks awarded and section B has 3 questions requiring full written solutions. Question papers and answers sheet will be available via a download from your Challenges Profile, which we will set up for you after entry.
All answers sheets and written solutions will need to be returned to us via by upload rather than sent back in the post. More details on this system will be available from your Challenges Profile.
How do I take part?
The competition is open to eligible students and those entered at the discretion of their schools.
We invite around 1000 qualifying students from the Senior Mathematical Challenge to take part in the British Mathematical Olympiad Round 1. Students who did not take the Senior Mathematical Challenge, or who did not reach the qualifying threshold, may be entered into the competition at the discretion of their school.
Invitations to participate in BMO1 will be clearly indicated in your results from the Senior Mathematical Challenge. Question papers will be available to download before the Olympiad date.
What happens after the British Mathematical Olympiad Round 1?
The top 25% of scorers receive a Certificate of Distinction; the next 45% receive a Certificate of Merit.
Around 100 eligible top-scorers will go on to sit the British Mathematical Olympiad Round 2.
How can I prepare for the British Mathematical Olympiad Round 1?
Students preparing for the competition should look at our guidance and past British Mathematical Olympiad Round 1 papers.
We also sell books which can help students to prepare for our competitions.
