Respiration in Unit 2 — Biology IAL Past Papers

12 papers, 2018–2025 · Unit 2

The Biology IAL Unit 2 — Cells, Development, Biodiversity and Conservation past papers in the collection that assess respiration.

By unit: all units (47) · Unit 1 (4) · Unit 2 (12) · Unit 3 (1) · Unit 4 (6) · Unit 5 (16) · Unit 6 (8)

These papers were matched to respiration automatically, by keyword patterns in their questions and mark schemes. A hand-check of 65 randomly chosen matches, read against the source question papers, found 53 that genuinely assess the topic and 12 that do not — 81.5% (95% confidence interval 70.4–89.1%). That is a good way to find practice on a topic, not proof a paper covers it, and a paper missing from this list may still assess it. A separate check found real papers that assess a topic without being tagged for it.
