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.

Before 2003 there was a single Kangaroo and Olympiad round for all year groups and we do not have not been able to find qualification details or boundaries.
What Should I Do Next?
If you’re happy with your score: Great! Consider trying our free practice course to maintain your skills or live classes to push even further next year.
If you want to improve: Our Go for Gold course gives you systematic teaching across all IMC topics, or join live classes for expert coaching.
If you qualified for follow-on rounds: Congratulations! See our Kangaroo and Olympiad preparation materials and courses.
📝 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.
