Instructions:
Put your name and student ID number on both the test and
the scantron.
On your scantron, bubble in your student ID number. Bubble in the test
version.
Only use pencil (spare ones up front). Erase stray marks fully. No stray marks
in the row of black lines.
On your scantron, identify the letter of the choice that best
completes the statement or answers the question.
If you think there is an error on the test,
make a note on your test (not the scantron) and tell the instructor on the way out.
Double
check your scantron for "double bubbles" or missing answers. There is no penalty for
guessing.
