Paper format. 16-Mec-B4 Integrated Manufacturing Systems, National Exams May 2018 — a three-hour open-book examination; any non-communicating calculator is permitted. The cover page states that “Five (5) questions constitute a complete paper. There are only five (5) questions” and that “All questions are of equal value”, so every question carries 20 marks against a 100-mark paper. Note 1 invites the candidate to submit a clear statement of any assumptions made where a question is open to interpretation — this paper needs that licence twice, and both places are flagged below in a Check box. Note 4 warns that some answers are wanted in essay form, where clarity and organisation carry marks. All five questions are worked here.
