Australian Intermediate Mathematics Olympiad (AIMO) is a highly challenging maths competition designed to identify and stretch talented students. The AIMO paper is pitched at a Year 10 level but may also be of interest to motivated and talented students in years 7 to 9 looking to pursue Olympiad-level mathematics.

AIMO may be suitable to students who have: 

  • an interest and aptitude for more complex mathematical problem solving
  • completed later stages of the AMT’s Maths Enrichment program
  • scored very highly in the Australian Mathematics Competition
  • undertaken substantial extension work outside of the curriculum.

AIMO results are used to identify students for selection in the Australian Maths Trust’s invitational high-performance programs

Like all our competitions, the AIMO contains unique problems designed each year by leading educators and academics to challenge and assess students’ problem-solving skills.

The questions range in difficulty. It is expected that only a small number of students will be able to complete the whole paper. As an indication of the type of questions asked and their level of difficulty, please see the sample AIMO papers below.
