IB Biology is one of the most popular Group 4 (Experimental Sciences) subjects in the International Baccalaureate Diploma Programme. It is offered at two levels: Higher Level (HL — 240 hours) and Standard Level (SL — 150 hours). Students study core topics including cell biology, molecular biology, genetics, ecology, evolution, and human physiology, alongside extended higher-level content for HL students.
The first assessment of the new 2025 IB Biology syllabus took place in May 2025. The new syllabus reorganizes content around four themes — Unity and Diversity, Form and Function, Interaction and Interdependence, and Continuity and Change. Paper 3 (options) has been removed, and assessment is now structured across two papers, with the Internal Assessment (IA) contributing 20% of the final grade.
A strong IB Biology grade opens doors to university medicine, biological sciences, biotechnology, veterinary science, psychology, environmental science, and dentistry. Top universities in the UK (Oxford, Cambridge, Imperial), USA (Harvard, Stanford, MIT), Canada (Toronto, McGill, UBC), Singapore (NUS, NTU), and Australia (Melbourne, Sydney, ANU) recognize IB Biology HL — especially a grade of 6 or 7 — as evidence of rigorous science preparation.

The IB Biology Diploma Programme is a two-year course offered at Standard Level (150 teaching hours) and Higher Level (240 teaching hours). It covers core topics like cell biology, genetics, evolution, ecology, and human physiology, plus a mandatory Internal Assessment (20% of grade) and optional Extended Essay. Students are assessed through external exam papers and the Internal Assessment.
The 2025 IB Biology syllabus is reorganized around four themes — Unity and Diversity, Form and Function, Interaction and Interdependence, and Continuity and Change. Paper 3 (options) has been removed, assessment is now split across two papers, and Internal Assessment criteria give more weight (around 50%) to Conclusion and Evaluation. First assessment is May 2025.
IB Biology HL (Higher Level) covers 240 teaching hours with additional higher-level content (AHL topics) such as nucleic acids, metabolism, plant biology, and animal physiology. SL (Standard Level) covers 150 hours focused on core topics. HL is recommended for students pursuing medicine, biotechnology, or biological sciences at university.
The IB Biology Diploma Programme runs over two academic years. Students begin in Year 1 (Grade 11) with foundational topics and typically start their Internal Assessment. Year 2 (Grade 12) focuses on advanced topics, IA completion, and exam preparation. Final assessments are in May or November of Year 2.
