*In 2025, due to a clash of school holidays, schools in China participated in an alternative IMC Paper, hosted by ASEEDER. The certificate thresholds were: Bronze 54+, Silver 69+, Gold 89+
Intermediate Maths Challenge Grade Boundaries and Qualification Thresholds
I'm often asked to guess what will this/next year's boundaries - my best guess is always that they will most likely be similar to the last few years, but I don't have any more info than that. This table will be updated as soon as possible once the boundaries are released.
On a phone, scroll the table sideways to see the Kangaroo and Olympiad thresholds.

Before 2003 there was a single Kangaroo and Olympiad round for all year groups - we do not have qualification boundaries for these years.

Qualified for Kangaroo or Olympiad Rounds?
Congratulations! The follow-on rounds are a fantastic opportunity to push your mathematical thinking further.
We have preparation resources for the Grey and Pink Kangaroos and Cayley, Hamilton and Maclaurin Olympiads:
- Free practice courses with past paper video solutions
- Live preparation classes running each year in February/March
Just missed the threshold? You may still be able to enter through discretionary entry - see below.
Missed the Kangaroo or Olympiad threshold?
Don't give up yet - you might still be able to enter!
Schools can enter students through discretionary entry if you were close to the automatic qualification mark. This is especially common for:
- Students 1-3 marks below the threshold
- Younger students who showed strong performance
- Students who missed the IMC but still want to take the follow-on rounds.
What to do:
- Check the grade boundaries above to see how close you were
- Speak to your maths teacher or head of department
- Ask if your school will support a discretionary entry
- If they agree, they can enter you when registrations open
Want to prepare anyway? Our Kangaroo and Olympiad courses welcome both automatic qualifiers and discretionary entries.
