Olympiad Mentoring Schemes (8 August 2023)

BMO EC is pleased that the Olympiad Mentoring Schemes are restarting for the academic year 2023/24.

• Students aiming to improve towards BMO2 level are welcome to sign up for the Olympiad Mentoring Scheme (OMS). All students will receive the monthly material but, depending on numbers, it may not be possible to offer all students a mentor. The form should be completed by a teacher at the applicant’s school.
• The Advanced Olympiad Mentoring Scheme (AOMS) is by invitation only, to students who attended the Hungary camp or the Cambridge camp in 2022/23 or who achieved a high score of at least 50/60 in BMO1 or 25/40 in BMO2. The form should be completed by the student.

The schemes will start in early September. Applications received after Monday 28th August may not be prioritised for mentor allocation.

We will be contacting former A/OMS mentors shortly, as well as any volunteers who have expressed an interest in joining this programme. Further expressions of interest are welcome via UKMT’s volunteering manager [volunteering@ukmt.org.uk].
