an HB pencil. Marks made with a pen will NOT be sensed. Erasures must be thorough or
the scanner will still sense a mark. Do NOT use correction fluid on the sheets. Do NOT put
any unnecessary marks or writing on the sheet. 1. On SIDE 1 (red side) of the form, in the
top box, in pen, print your student number, name, course name, and the date in the

SIGNATURE.
2. In the second box, with a pencil, mark your student number and the exam version
number in the space provided. If your student number does NOT begin with a 4, put “00”
before your student number. Then fill in the corresponding bubble numbers underneath. Do
not put in a leading zero when bubbling in your version number.
3. Answers: mark only ONE choice from the alternatives (A,B,C,D,E) provided for each
