Exam II Rules and Question Distribution

Exam Time

Exam Rules
By using the following exam rules, it could greatly simplify and flex the exam taking (e.g., more time could be given if needed), and make you feel more comfortable while taking the exam. Therefore, please be honest because we want to avoid using a much stricter method like ProctorU.

The whole exam will be monitored from Zoom. Finish setting up and signing in to the Zoom (at https://und.zoom.us/j/2489867333) 30 minutes before the exam.

Have to use your real name, not nickname, for Zoom, so the instructor can identify the students correctly.

Turn on the webcam and speaker, mute the microphone, and keep them active during the exam. Take one of the following approaches:

If you have a printer and a wired/wireless webcam (or two computers), point the webcam to show you, (exam) paper, desk, computer (if for Zoom), and scanner or phone (if for photoing the answers), like the figure above.

If you have a wired/wireless webcam, point the webcam to show you, (exam) paper, desk, computer (for exam questions), and scanner or phone (if for photoing the answers).

If you have a phone installed with Zoom, point the phone to show you, (exam) paper, desk, computer (for exam questions), and scanner or phone (if for photoing the answers).

If you have a computer webcam, point the webcam to show you, (exam) paper, desk, and scanner or phone (if for reading the exam questions or photoing the answers).

If you do not have anything, 🤐

The .pdf exam will be emailed to your UND email account a few minutes before the exam time.

Start the exam as soon as you receive it. You can either
1. Print the exam and write the answers on the exam, or
2. Read the exam questions from the computer or phone and write the answers on papers.

It is an exam of closed books and notes. During the exam, you are NOT allowed to use the computers, keyboards, mice, and cell phones, other than reading the exam questions or communicating with the instructor. All communications are through Zoom chat. In addition, you can only leave your seat after asking.

At the end of the exam, you can either
1. Scan the exam or papers, or
2. Take pictures of the exam or papers.
Make sure the result files are correct and clear!

Submit the files via either one of the following two methods immediately:
- Upload them to the Blackboard or
- Email them back to the instructor at wenchen@cs.und.edu .
Do not leave until you receive a confirmation from the instructor.

The exam will be highly suspected if fail to follow the above rules.
