Paper format. 04-Agric-A1 Animal or Human Physiology, National Exams May 2013 — a three-hour closed-book examination; one of two approved calculator models (Casio or Sharp) is permitted. The cover page states that five (5) questions constitute a complete exam paper and that only the first five as they appear in the answer book are marked, that each question is of equal value, and that full marks are not available for a bare correct answer — the reasoning must be communicated clearly. All six printed questions are worked here, because the set is a study resource rather than a timed attempt.
