Recursion — Computer Science IAL Past Papers

19 papers, 2021–2025 · Paper 3, Paper 4

Every Computer Science IAL past paper in the collection that assesses recursion.

By unit: all units (19) · Paper 3 (8) · Paper 4 (11)

• Paper 3: on 8 of 24 papers, 2–7 marks a paper (5 on average)
• Paper 4: on 11 of 24 papers, 6–14 marks a paper (10 on average)

Read question by question: blind checks found 116 of 120 question parts tagged with the right topic (95% confidence interval 91.7–98.7%). “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.
