Paper format. National Exams, December 2013 — 07-Mec-B4, Integrated Manufacturing Systems. Three hours; open book; any non-communicating calculator permitted. Seven questions are printed and any five constitute a complete paper, each of equal value (20 marks); only the first five appearing in the answer book are marked. Several questions call for an essay answer, where clarity and organisation carry marks. Note 1 of the paper invites the candidate to state any assumption made where a question is open to interpretation — that licence is used twice below and each use is flagged. All seven questions are worked here, so the set can serve as a complete study resource.
