Questions & answers
Frequently asked questions
How do HL and SL Biology differ?
HL covers the themes in greater depth and has longer examinations. Paper 1 contributes 36%, Paper 2 44% and the scientific investigation 20% at both levels.
What changed in the revised Biology course?
First examined in May 2025, the course uses four themes: Unity and diversity; Form and function; Interaction and interdependence; and Continuity and change. Paper 1 has 1A multiple-choice and 1B data and experimental questions; the former options and Paper 3 were removed.
What is the Biology IA?
It is a student-designed scientific investigation written up as a report. The teacher marks it and the IB moderates samples. Assessment considers research design, data analysis, conclusion and evaluation.
What is Paper 1B?
It focuses on data and experimental work, including interpreting graphs, processing data and evaluating methods in unfamiliar contexts.
Do I need HL Biology for medicine?
Medicine programmes commonly require HL Chemistry, and many also require HL Biology or another science. Check the current entry requirements of each university.
