National Exams, December 2014 — 07-Mec-B5 Product Design and Development. Three hours. Open book; no calculator permitted. Question 1 must be completed and is worth 40 marks; four of the six remaining questions are chosen, each worth 15 marks, for 100 marks in total. Only the first five questions as they appear in the answer book are marked, and the paper states that most answers are expected in essay form or as tables, figures and charts, with clarity and organisation carrying weight.
The paper prints 40 + 6 × 15 = 130 marks and a candidate attempts 40 + 4 × 15 = 100 of them. All seven questions are answered below, because this set is a study resource rather than an examination script. The published marking scheme on the last source page splits Question 1 as 6 / 9 / 9 / 6 / 4 / 6 and each 15-mark question into its own parts, and the answers below are proportioned to that split. The arithmetic is kept deliberately light — no calculator is allowed.
