BMO Round 2 (25 January 2019)

This year’s BMO Round 2 paper was taken yesterday.

BMO Round 1 marked (7 January 2019)

BMO Round 1 was marked in Cambridge on 7–9 December. Gold medals are awarded for scores of 48 or more, silver medals for scores of 41 to 47, bronze medals for scores of 35 to 40, certificates of distinction for scores of 22 and above, certificates of merit for scores of 9 to 21. The report for schools, with statistics on results, is also available.

The BMO2 qualifying cut-off scores are 35 for students in year 13 (England and Wales), year S6 (Scotland), year 14 (Northern Ireland); 32 for students in year 12 (England and Wales), year S5 (Scotland), year 13 (Northern Ireland); 29 for students in year 11 (England and Wales), year S4 (Scotland), year 12 (Northern Ireland); and 26 for students in lower school years. Scoring at least the cut-off on BMO1 gives free entry to BMO2 provided that the candidate is eligible to represent the UK at the IMO. Any participant in BMO1 may enter BMO2 by paying the entry fee. BMO2 will take place on 24 January.
