Read these notes carefully. Write your name, class and index number above. There are thirty 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 shade your choice in soft pencil on the separate Optical Answer Sheet. Each correct answer will score one mark. A mark will not be deducted for a wrong answer. Any rough working should be done on the Question Paper. The use of an approved scientific calculator is expected where appropriate. Hand in the Optical Answer Sheet. _________________________________________________________________________ This document consists of 15 printed pages.
