National Exams May 2019 — 17-Ind-A6, Systems Simulation, 3 hours duration. Section A: do 3 of 5 (30 marks); Section B: do 1 of 2 per the front-page summary table — the Part B section instructions on the page itself read “do 2 of 3” instead, a genuine inconsistency in the source paper's own front matter (flagged below); Section C: do 1 of 2 (20 marks). This study resource answers all ten questions across the three parts.

Check — front-page/section instructions disagree. The cover page's summary table states “Section B: Do 1 of 2 Questions, Total marks: 20,” but Part B's own section banner (page 4) reads “Complete two of the following three sets of questions,” and Part B in fact contains three questions worth 15 marks each. The cover page's own overall total (70 marks across “5 Questions”) is likewise only consistent with the “2 of 3” reading (30+30+... does not match 70 either way exactly, since 30(A)+2×15(B)+20(C)=80, one section choice short of 70); this is an internal inconsistency in the exam's own printed materials. All three Part B questions are answered in full below regardless.
