Paper format. National Examinations, December 2014
— 98-Civ-B7 Highway Engineering. Three-hour, OPEN BOOK paper;
any non-communicating calculator permitted. Seven questions of equal value; a total of five
solutions constitutes a complete paper, and only the first five in the answer book are marked.
The grading scheme printed on page 1 splits the marks as Q1 (15+5), Q2 (12+8), Q3 (20),
Q4 (10+10), Q5 (10+10), Q6 (6+14), Q7 (5+15). Note 1 invites the candidate to state any
assumption made about an ambiguous question; Note 2 permits any required datum that is not
given to be assumed. All seven questions are solved here, because the set is
a study resource rather than a timed attempt.

Check — source check. The only defects on page 5 (Questions 6 and 7) are two typographical errors in
the printed paper itself (“horizintal” for horizontal and “Detrmine” for
determine). No question data is in doubt. Where the paper omits a datum the assumption made is
stated in a callout beside the calculation, as Note 2 of the paper permits.
