International Mathematical Olympiad (IMO)

The UK has been competing at the IMO since 1967. Since 1991 this participation has been organised by the BMOC/BMOS; each year, a Leader’s report is produced. Some other reports are also available where more than one report, or unofficial reports, were produced for a given year. An olympiad photo gallery is also available.

At the end of the Trinity olympiad training and selection camp, a squad of 8 or 9 people is selected, from which the final team of 6 and 2 or 3 reserves are selected at the Tonbridge camp at the end of May.

At the IMO, there are two papers, each of three questions, with each question marked out of 7 points. For past papers, see the official IMO site.
