For the exam, you may use *one sheet of notes* that you wrote yourself;
please take a scan or a picture of this (both sides)
and submit it on Canvas.
However, you may not use your book or anything else not written by you.
You certainly should not talk to other people!
Calculators are allowed (although you shouldn't really need one).
but not communication devices (like cell phones).

The exam consists of questions similar in style and content to those in the practice exam on MyLab.

The final exam will be * proctored*.
If you have access to a computer with a webcam,
then you can schedule a time with me to take the exam in a Zoom meeting.
If you're near Lincoln,
then we can schedule a time for you to take the exam in person.
If you're near any of the three main SCC campuses
(Lincoln, Beatrice, Milford)
and available on a weekday,
then you can schedule the exam at one of the Testing Centers.
If none of these will work for you,
then contact me as soon as possible to make alternate arrangements.
