Write your name, entre number and candidate number on the nswer Sheet in the spaces provided unless this has been done for you. There are forty questions on this paper. nswer all questions. For each question there are four possible answers,, and. hoose the one you consider correct and record your choice in soft pencil on the separate nswer Sheet. Read the instructions on the nswer Sheet very carefully. Each correct answer will score one mark. mark will not be deducted for a wrong answer. ny rough working should be done in this booklet. copy of the Periodic Table is printed on page 20.
