This booklet consists of 14 printed pages MERIDIAN JUNIOR COLLEGE JC2 Preliminary Examinations Higher 1 H1 Physics 8866/01 Paper 1 Multiple Choice 22 September 2016 1 hour Additional Materials: Multiple Choice Answer Sheet Class Reg No Candidate Name: READ THESE INSTRUCTIONS FIRST Write in soft pencil. Do not use staples, paper clips, glue or correction fluid. Write your name, class and index number on the Answer Sheet in the spaces provided. In the Index Number section, shade your index number using the first two spaces (e.g. index number 5 should be entered as “05”). Ignore the remaining numbers and letters. 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 record your choice in soft pencil on the 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 in this booklet. The use of an approved scientific calculator is expected, where appropriate.
