On the scan-tron, please write your name and student 1D# (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 (“002”).
