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 exam-style AIO problems 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.

More than lessons — a platform built to keep them going.

Real streaks, real checks, real progress — and a parent view, so you always know it's working. Here's what your child (and you) actually see.

Built-in motivation

A streak they don't want to break.

Coding rewards consistency. Daily streaks, XP and a pet companion turn "I should practise" into "I want to keep my streak" — the habit does the work for you.

  • Daily streaks & XP that build the habit
  • A growing pet companion that levels up as they do
Ace Achievers streak — daily practice streak and XP
AIO Algorithms mastery check — a 12-question quiz at the end of a topic
Checked, not just watched

Every topic ends with a mastery check.

It's easy to nod along to a video and learn nothing. So each topic closes with a mastery quiz — your child has to actually choose, reason and pass before moving on.

  • Multi-question mastery checks, 70%+ to pass
  • Write-and-run code exercises checked instantly
Visible progress

Every step forward, on one screen.

No guessing where they're up to. The dashboard shows each course, each lesson done, and what's next — so momentum is something your child can see and feel.

  • Per-course and per-lesson progress, always up to date
  • Pick up exactly where they left off, on any device

The Parent View

Screen time you can finally trust.

You hold the account — so when your child is at the computer, you know it's real learning, not a game tab in disguise. The parent report shows time online vs real focused time, lessons done and a focus rate — no hovering required.

  • Real focused time vs total time — quality, not just minutes
  • A clear daily & weekly picture of genuine study
