Write your name, Centre number and candidate number in the spaces at the top of this page. Write these details on your answer sheets if they are not already printed. Answer all questions. Write your answers clearly on the separate answer sheets. Use a pencil. You may use the question paper for any rough work, but you must write your answers in pencil on the answer sheets. You will have no extra time for this, so you must finish in one and a half hours. At the end of the examination, you should hand in both the question paper and the answer sheets
