On the scan-tron, please write your name and student ID# (CWID) in the appropriate sections. After your student ID#, LEAVE A BLANK SPACE and then fill in your lab section number as follows: 01 = Tuesdays 9:30 05 = Wednesdays 12:30 10 = Thursdays 6:30 02 = Tuesdays 12:30 06 = Wednesdays 2:30 12 = Fridays 8:30 03 = Tuesdays 2:30 07 = Thursdays 9:30 11 = Tuesdays 6:30 08 = Thursdays 12:30 04 = Wednesdays 8:30 09 = Thursdays 2:30 Be sure to fill in all of the corresponding circles. This will allow the TA’s to return your scores in lab. Grades also will be posted on D2L. 2. On the scan-tron, write “3204” for “Course Number”, and for “Sec.”, write the Form # of this exam (“001”). 3. There are a total of 43 regular questions on this exam, and each question is worth .2 points unless noted otherwise (100 points total). There are also 2 extra credit questions, each worth 2 points. 4. If you have a question, please raise your hand and we will come to you. 5. When finished, please turn in the scan-tron TO YOUR LAB TA. You can keep this exam copy. 6. Good Luck! These instructions are given for good reason — failure to follow them could result in up to a 10 point reduction in yOur grade. *By taking this exam, you consent to OSU’s Commitment to Academic Integrity: L “I will respect OSU’s commitment to academic integrity and uphold the values of honesty and responsibility that preserve our academic community.” Page 1 of 8 to-NAUH’: CABT‘ LN; ' Mg l 2 l l weave-us CONNECfiUEW eprrmcam, acumen-er (ngfi) 1.
