Multi-choice question answer sheets should be completed using a 2B pencil as these are marked by a computer system. Ensure you also have an eraser so that you can cleanly change your answer if needed. Do not draw anywhere else on the answer sheet.
The instructions given to candidates for written answers state: "Write in ink on both sides of the paper. Marks are deducted for writing which is not easily legible. (Pencils may be used for diagrams, graphs, or for completing multi-choice question answer sheet to be computer marked.)"
It is highly recommended that you use pen for your written answers (unless otherwise stated) as this is permanent on paper in comparison to pencil. However, an answer written in pencil will still be marked.
