KEEP YOUR ANSWERS AND ANSWER SHEET COVERED AT ALL TIMES 1 READ THE DIRECTIONS BIOLOGY: A HUMAN APPROACH EXAMINATION II NAME____________________________ EBIO 1030, SECS. #0001 & #0002 Monday, November 4, 2013 INSTRUCTIONS: Use a SOFT-LEAD pencil (#1 or #2) for writing in and mark-sensing your name, CU I.D. number, lecture section number and answers on the exam answer sheet, erasing completely when necessary. For the lecture section, use either 0001 or 0002 in the “1,2,3,4” slot on the top left of the answer sheet. An answer key, your percent exam score and the grade cut-offs you will need to calculate your grade will be posted on D2L ASAP. Be sure to guess any time you don’t know an answer. There are no deliberately tricky questions, so if something doesn’t make sense to you, ask one of the proctors. On the bottom of your answer sheet you may defend your answer to any question you feel is ambiguous, but you must first mark-sense your best guess among the choices. To ensure your not running out of time, complete the entire exam before defending a specific answer. Expect to have the equivalent of one question deducted from your exam score if you are not taking the exam in the proper location (See below)! Your cell phone is to be turned off and if you must wear a hat, turn the bill to the back. You are not to use iPods, cell phones, iPhones, digital media players, Zunes, Blackberrys, computers, calculators or mobile devices of any kind during this exam. There cannot be any earphones, earpieces, etc., in or around your ears at any time. Any answers you have put on your answer sheet or exam are to be covered in such a way that no one can see them, and do not let your eyes wander.
