The affiliate ID is the second sequence of numbers on your University ID card.

If it does not, your exam will be graded with the wrong key. For most people, this is bad… • Use only a #2 pencil. Do not use pens, crayons, motor oil, or grape juice. • Do all calculations on the exam pages. Do not make any unnecessary marks on the answer sheet. • This exam consists of 25 multiple-choice questions worth 4 points each. There are 9 total pages (including the cover sheets & periodic table). Make sure you have all the pages you’re supposed to. • Choose the one best answer to each of the questions and mark your selection on the Scantron sheet. Read all responses before making a selection. Do not mark more than one selection . • When you are finished, turn in both your Scantron and exam booklet to your TA.
