IOAA Exam Pattern

Below, you’ll find the breakdown of the IOAA exam pattern.

IOAA Exam Pattern
Duration	Each paper 5 hours
Number of exams	2 papers
Type	Theory, Practical

The first part of the IOAA is about theory, where you’ll encounter both short and longer questions. Here’s how they’re divided:

Quick questions: There are five of these.
Medium-length questions: You’ll find five of these in the paper.
Longer questions: Expect to see two or three of these.

The whole event lasts for 5 hours.

Now, let’s talk about the practical part, which is a big deal in the IOAA. It’s divided into different sections, and the tasks might vary slightly from one exam to another. Usually, students get tasks from one or more categories, but sometimes they might have to tackle assignments covering all four areas. The IOAA curriculum covers everything you need to know about:

Observation
Paper-based practical problems
Computer-based problems
Planetarium simulations
