Paper format. National Examinations, December 2016 — 98-Civ-B10 Traffic Engineering. Three-hour duration; OPEN BOOK, any non-communicating calculator permitted. Seven questions, all of equal value (20 marks each), with the mark split printed in the paper’s own grading scheme: Q1 and Q2 and Q5 are (a) to (e) at 4 marks each, Q3 and Q4 are single 20-mark questions, Q6 is (a) 6 marks with (b) and (c) 7 marks each, and Q7 is (a) to (h) at 2.5 marks each. The paper states that a total of five solutions is required and that only the first five in the answer book will be marked. All seven questions are solved here, because this set is a study resource rather than a sitting. The paper also permits assumptions — “Any data required, but not given, can be assumed” — and every assumption made below is stated explicitly where it is used.
