By unit: all units (106) · Unit 2 (31) · Unit 3 (20) · Unit 4 (31) · Unit 6 (23) · Unit 7 (1)

Unit 3: on 20 of 32 papers, 1–5 marks a paper (2 on average)

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.
