Do not use staples, paper clips, glue or correction fluid. Write your name and index number on the Answer Sheet in the spaces provided unless this has been done for you. There are twenty questions in this section. Answer all questions. For each question there are four possible answers A, B, C and D. Choose the one you consider correct and record your choice in soft pencil on the separate Answer Sheet. Read the instructions on the Answer Sheet very carefully. Answers to Paper 1 and 2 must be handed in separately. You are advised to spend no more than 30 minutes on Paper 1. You may proceed to answer Paper 2 as soon as you have completed Paper 1. Each correct answer will score one mark. A mark will not be deducted for a wrong answer. Any rough working should be done in this paper. The use of an approved scientific calculator is expected, where appropriate. Setter(s): Mr Abdul Malek Osman This document consists of 9 printed pages.
