IB Biology
IB Biology (IB Bio) is the study of living organisms and diverse forms of life on Earth - from microscopic bacteria to complex multicellular organisms like humans. The depth of knowledge required in IB Biology extends beyond a typical high school biology course, as students are required to have a comprehensive understanding of content and to explore the connections between different areas of biology. Furthermore, students develop critical thinking and analysis skills throughout the course.
Course Structure and Content
Starting with the May 2025 cohort, IB Biology follows a new syllabus offered at both Standard Level (SL) and Higher Level (HL). SL students complete 150 teaching hours plus 40 hours of experimental work, while HL students complete 240 teaching hours and an additional 60 hours of experimental work. A key update to the syllabus is the removal of option topics and the reduction of examination papers from three to two.
The course is structured around four themes: Unity and Diversity, Form and Function, Interaction and Interdependence, and Continuity and Change. Each theme is explored across four levels of organisation: molecules, cells, organisms, and ecosystems.
The course spans two years, culminating in external examinations featuring multiple-choice, short-answer, data-based, practical-based, and extended-response questions. HL Biology covers more breadth and depth compared to SL Biology.
The experimental component builds essential skills in laboratory techniques, experimental design, data logging, analysis, and interpretation using models, simulations, and databases. An important internal assessment (IA) involves planning and conducting an individual practical investigation.
