What is the Australian Informatics Olympiad?

Understand the exam before you choose your path.

The competition

The AIO is Australia's national school programming competition, run online by the Australian Mathematics Trust on the ORAC judging platform. You write programs that read input and print answers, and ORAC grades them automatically against many secret test cases.

  • Format Online, ~3 hours, sat at school or home
  • Problems 6 problems, increasing in difficulty
  • Subtasks Each problem is split into subtasks — you bank partial marks for partial solutions
  • Languages Python, C, C++ and more (we teach in Python)
  • Who Any secondary student — no contest experience needed

Where it leads
1 AIO — the entry-point national contest
2 AIIO — the invitational round for top scorers
3 Selection School — the Australian training squad
4 IOI — the International Olympiad in Informatics

Strong AIO results are the first rung on the ladder to representing Australia — and a standout signal on any university or scholarship application.

How It Works

Built for self-study — every lesson teaches, then makes you do.

⚡ Write code, press run, see it pass — right in the lesson

Every lesson carries a real Python runtime in the browser. You read the teaching, then write your own solution and run it on the sample cases — no setup, no installs. Worked examples are walked through with the 6-step method (read → calculate by hand → key observation → is it fast enough? → frame it → code it), and the Advanced course is built on real AIO past papers with two write-and-run exercises each.

The whole line teaches the exam's real scoring logic — bank the subtasks first, then chase full marks — so you convert what you know into actual points on the day.
