International Biology Olympiad 2024

The International Biology Olympiad is a competition for secondary school students. The competition occurs annually in July and is hosted by one of the member countries of the IBO Association. This year, the IBO 2024 is organized by the Ministry of Education of the Republic of Kazakhstan. Through this competition, students' ability to tackle biological problems and conduct experiments is assessed. Interest in Biology, creativity, inventiveness, and perseverance are essential for participants. Each member country nominates four students who are winners of their national competitions. In this article, we will explore the International Biology Olympiad (IBO) exam, its structure, the topics covered, and its significance in promoting Biology education and fostering international scientific collaboration.

1.0About International Biology Olympiad 2024

The International Biology Olympiad (IBO) is like a big science competition for high school students worldwide. It tests their understanding of biology. This year's IBO in 2024 is all about bioinformatics, a mix of biology, math, statistics, computer science, and data science. It's happening in Astana, Kazakhstan.

The main goals of the IBO are:

  • To get more people interested in biology and related sciences.
  • To give students from different countries a chance to compete together.
  • To inspire more research and progress in biology.

3.0International Biology Olympiad Syllabus

Contrary to popular belief, IBO does not have a fixed syllabus or curriculum. This means that students cannot simply memorize a set list of topics and expect to excel in their IBO exams. Despite that, regulations define the required content and skill set for these exams.

Theoretical exams

Theoretical tasks in the IBO aim to assess competitors' comprehension, processing abilities, and application of biological knowledge. They should cover the following topics in the specified proportions.

Theoretical Exam Topics
