READ THESE INSTRUCTIONS FIRST Write in soft pencil. Do not use staples, paper clips, glue or correction fluid. Write your name, Centre number, index number and class on the Answer Sheet in the spaces provided. There are twenty questions on this paper. 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 Paper 2 must be handed in separately. Each correct answer will score one mark. A mark will not be deducted for a wrong answer. 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. Any rough working should be done in this booklet. The use of an approved scientific calculator is expected, where appropriate. Setter: Mr LH Liang This document consists of 11 printed pages and 1 blank page.
