 Answer all 38 questions or as many as you can.
 Each question carries equal marks (+1). Circle only the right answer.
 Wrong answers will be negatively marked. (1/4 for each wrong answer).
 Circling two choices will be considered as a wrong answer.
 If you circle the wrong box, write “cancel” to cancel it.
 Do not attempt to copy. Your neighbor may have a different ordering of questions and answers.
 Any attempt to copy answers from another candidate will result in permanent disbarment from the University for all purposes.
 No Books or calculators are allowed.
 GIVE ALL ANSWERS ON THIS SHEET ONLY. The remaining sheets are not to be submitted – you may take them with you.
