The mid-term exam will consist of ~ 70 multiple-choice questions of
similar format. This will be a closed book exam, no calculator is
allowed. Each student will receive a question packet and a Scantron
sheet. Indicate all your answers on the Scantron sheet. On the answer
sheet, fill in the blocks carefully with no stray marks. Use pencil so
that you can erase mistakes cleanly. Put your name and student
number on both the Scantron sheet and the question packet. There is
only one best answer for each question. In one of the classes before the
mid-term, the instructor will demonstrate how the Scantron sheets
should be filled out.
