IBO Syllabus

The IBO is an association that organises annual Biology competitions for secondary school students. It is one of the most popular International Science Olympiads. The first IBO exam was held in Czechoslovakia in 1990, and to date, the exam is conducted annually. The competition has students participating across 75 countries and five continents. All participating countries send the four winners of their National Biology Olympiad to the IBO. These students are accompanied by two adults who are members of the international jury for the duration of the competition.

About the Examination

One must have heard of many olympiad exams, and IBO is also one of the prominent olympiad exams that emphasise biology. First of all, the IBO full form is the International Biology Olympiad. The learner who is keen on learning about anatomy and knows the biological facts of animals and plants can take this examination and pursue a career in the biology field. As we all know that biology is a vast subject with many branches such as botany, zoology, anatomy, physiology, biotechnology, ecology, immunology, genetics and microbiology. The IBO exam is a combination of all these subjects. A student with an interest and curiosity to learn in any of these branches of biology can write the exam.

Purpose of IBO

The main purpose of this olympiad exam is to inspire and empower the upcoming generation in the field of life sciences and showcase their talent on an international platform. Listed below are the few purposes of the IBO examination.

  • The main motto is to respect the curiosity and eagerness shown by the candidate in the life sciences subject.
  • To enrich young biologists and young scientists to develop their interest in this field.
  • To bring closer connections to frame an international network of biology scientists and their talent and future biologists.
  • To recognise highly gifted biology students and to promote their talents in the long run.
  • To develop intercultural conversations and nations by taking biology students from around the world and develop strong bonds between the countries worldwide.
  • To set up high standards in the field of education and evaluation of highly dexterous biology students.
  • The Olympiad exam brings out the opportunity to compare the syllabi and educational trends of biology on a global aspect across different countries.
  • To promote and boost the exchange of ideas and knowledge about life sciences.

Highlights of the examination

The International Biology Olympiad is conducted once a year. The exam is held in July of every year.

  • All disciplines of biology are accepted for the IBO.
  • In addition, widely oriented topics should encourage the candidates to showcase not only their knowledge and skills but also their capability to think independently and creativity towards the new research and advancements.
  • The exam consists of two parts, namely the theoretical and practical parts.
  • The content of the theoretical part is the main syllabus for the examination, and the practical part includes the basic skills required for the life science subject.
  • There should be at least a one-day interval between the two sections of the examination.
  • In a practical examination, it is taken care that no experiments are carried out that cause deterioration of the living conditions of vertebrates.

Syllabus for the Exam

The syllabus plays an important role in the preparation of any examination. A prescribed syllabus is framed for every exam. The IBO exam syllabus is designed in such a manner that students taking the examination from any country can study easily as per the curriculum. The syllabus includes various topics, such as cell biology, molecular biology, plant anatomy and physiology, animal anatomy and physiology, ethology, genetics and evolution, ecology, and biosystematics.

Syllabus for Theoretical Examination

The questions in the theory test are separately grouped by domains with different preference and weightage for the topics depending on the concepts.

  • Cell biology has a weightage of around 20% in the examination.
  • Animal anatomy & physiology has a weightage of around 25% in the examination.
  • Plant anatomy & physiology has a weightage of around 15 % in the examination.
  • Ethology has a weightage of around 5% in the examination.
  • Genetics & evolution has a weightage of around 20% in the examination.
  • Ecology has a weightage of around 10% in the examination.

Tips to Study for the Examination

As the exam indicates it is an international exam, one may feel nervous and wonder how to study. Listed below are a few tricks to crack the examination easily

  • Learn the syllabus as per the weightage. The topic with more weightage can be studied on priority.
  • Practise more questions and solve numerous sample papers and previous years’ papers to get acquainted with the exam pattern.
  • Solving more questions helps the student to know about the difficulty rating of the exam.
  • More focus can be given to important concepts such as scientific names, classification of organisms and diagrammatic-based questions.
  • The student has to understand the life process such as photosynthesis, digestion in animals and another process rather than mugging up instantly.
  • To improve practical skills, the student can perform experiments in labs and improvise themselves.
  • Handling an apparatus, such as a microscope and slides, can be learnt by doing experiments, not by theoretical knowledge.
  • Time management plays an important role in the examination. Spending too much time on a single question is a waste of time; one has to move to further questions and come back to existing ones when done with other questions.
  • Key biology skills, such as diagrams, handling the equipment, and technical biology practical methods, must be grasped thoroughly for a smooth practical examination.
