Paper format. National Examinations, May 2015 — 98-Civ-B7 Highway Engineering. Three hours, open book, any non-communicating calculator permitted. Seven questions of equal value (20 marks each); a total of five solutions constitutes a full paper, and only the first five in the answer book are marked. All seven are solved here so the set works as a study resource. Note 1 of the paper invites a clear statement of any assumption made, and Note 2 permits any data required but not given to be assumed — both are used below and every assumption is flagged.
