• D1: on 14 of 14 papers, 9–19 marks a paper (13 on average)

Read question by question: blind checks found 383 of 390 question parts tagged with the right topic (95% confidence interval 96.3–99.1%). “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.
