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 (DjVu TBA).

The final exam will be * proctored*.
If you're near any of the three main SCC campuses
(Lincoln, Beatrice, Milford),
then you can schedule the exam at one of the Testing Centers;
it will automatically be ready for you at Lincoln,
but let me know if you plan to take it at Beatrice or Milford,
so that I can have it ready for you there.
If you have access to a computer with a webcam and mike,
then you can take it using ProctorU for a small fee;
let me know if you want to do this
so that I can send you an invitation to schedule it.
If you're near Lincoln,
then we may be able to schedule a time
for you to take the exam with me in person.
If none of these will work for you, then contact me as soon as possible!
