Document Summary

Make sure your answers are clearly marked by pencils. Otherwise, no marks will be given: choose only the best answer for each question, no credit will be given for anything written in the examination booklet. If you change an answer on the scantron, be sure that you erase your first mark completely; then blacken the circle of the answer choice you prefer. Your score will be based on the number of questions you answer correctly. No credit will be given for omitted answers; no credit will be lost for wrong answers: you must mark all your answers on the answer sheet during the allotted time.
