Practise IB Biology SL across four themes with questions that build biological terminology, data interpretation, calculations and mark-scheme reasoning before mixed-paper revision.
IB Biology SL follows four themes—unity and diversity, form and function, interaction and interdependence, and continuity and change—across molecules, cells, organisms and ecosystems.
The reviewed bank includes Paper 1A multiple-choice, Paper 1B data-based and Paper 2 data-based, short-answer and extended-response practice for the first-assessment 2025 course.
Start with one syllabus topic, attempt each question before checking the answer, then compare your terminology, calculations, data interpretation and explanation chain with the available mark guidance.
No. This SL route is bound to SL evidence; shared nodes have a separate HL route, while HL-only content is kept out of the SL question set.
