Groups 1 and 2 — Chemistry IAL Past Papers
73 papers, 2014–2025 · Unit 2, Unit 3, Unit 6, Unit 7
Every Chemistry IAL past paper in the collection that assesses groups 1 and 2.
By unit: all units (73) · Unit 2 (32) · Unit 3 (30) · Unit 6 (10) · Unit 7 (1)
Unit 2 : on 32 of 32 papers, 1–17 marks a paper (7 on average)Unit 3 : on 30 of 32 papers, 1–17 marks a paper (7 on average)Unit 6 : on 10 of 29 papers, 1–7 marks a paper (3 on average)Unit 7 : on 1 of 1 papers, 3 marks a paper
Read question by question: blind checks found 112 of 120 question parts tagged with the right topic (95% confidence interval 87.4–96.6%). “needs (a)” names an earlier part the listed parts build on, and “then (c)” a later part that continues from them, so a question can be worked through whole.
How topics are found and checked
