IBO Registration

Due to the current COVID-19 epidemic, the 32nd International Biology Olympiad in Lisbon, Portugal, has been cancelled. The competition aims to identify, promote, empower, and support the next generation of biological research leaders while also expanding their global network.

Czechoslovakia hosted the first International Biology Olympiad in 1990, and it has been held every year thereafter. From July 18 to 23, the virtual IBO 2024-25 Challenge will take place.

Following are the Conditions To Participate in the IBO Challenge 2024-25:

• You must be a member of the IBO Association in order to participate in the IBO challenge 2024-25.

• You should have an ongoing National Biology Olympiad (NBO) that will select your competitors.

• You must register your country by visiting the IBO Challenge 2024-25 official website.

Exam Pattern for IBO

The IBO test has a theoretical as well as a practical component. The theoretical tests encompass areas such as cell biology, molecular biology, plant and animal anatomy and physiology, ethology, genetics and evolution, ecology, and biosystematics. The marks are weighted so that each theoretical and practical component earns about half of the total.

All candidates are rated based on their individual scores. The top ten percent of students receive gold medals, the next twenty percent receive silver medals, and the next thirty percent receive bronze medals.

Note: Registration in the IBO Challenge 2024-25 will require a single fee of 150 (one hundred and fifty Euros). Each delegation can have up to 4 students and not less than 2 members of the Jury (There is no maximum limit for the Jury member. No extra will be required).

A delegation of a country or region consists of 1- 4 competitors (students selected by the National Biology Olympiad and a minimum of 2 members of the Jury).
