Where possible, we publish the exam papers from previous IBOs. Due to licencing, we cannot publish all old exam papers here – they are accessible only via password, which all member countries have. If you need specific materials, please contact us.
Please note: The available IBO examination questions are published under the Creative Commons license CC BY-NC-SA (Attribution-NonCommercial-ShareAlike). The exam papers can be used freely for educational purposes as long as IBO (International Biology Olympiad e.V.) is credited and new creations are licensed under identical terms. No commercial use is allowed.
Where "n/a" is listed, the papers are still in the 2-years-black-out period after the IBO in question (see IBO Operational Guidelines).
