COS 490/MAT 425: Computability and Complexity

Spring 2021

You are permitted to use our textbook, your notes, homework, and PDFs I've given you.
You are not allowed to use other resources (Internet search, friends, etc.) during the exam.
You may only use electronic devices (computer, smart phone) to the extent of following exam logistics (below).

The exam covers everything we have done, up to and including Section 9.6. (Section 5.1 will be on the next exam.)

The exam will take place during our usual class time. I will proctor you via Zoom.

Before class time:

Read this document carefully. Ignorance is not an excuse.
Prepare enough paper to write on.
On the first sheet, write at the top an academic integrity statement of your own devising. You should say that you didn't consult any unauthorized resources (Internet search, friends, other sources of help, etc.).
Sign your name after the statement.

At class time:

Join our usual Zoom meeting first.
Find a PDF of the exam questions on Moodle near the bottom; pull it up on your computer.
Work things out on notebook/blank paper. You do not need to print out the questions.
After you are done or the time is up, scan your work and upload to Moodle near the bottom.
Download your submission from Moodle to double check that you uploaded correctly.
You may leave early after you finish scanning and uploading your exam.

Scanning:

Here are instructions for how best to scan handwritten work using a smart phone.
It is different from simply taking pictures.
Familiarize yourself with the procedure to make sure you feel confident scanning your work.
If you would rather typeset your exam in LaTeX, be my guest.

Timing:

You have the full 50 minutes of class time for the exam.
To give you more flexibility, since this class is scheduled within the 70-minute B4 block, you may start up to 10 minutes early or end up to 10 minutes late, for a maximum of 70 minutes.
To accommodate for scanning, you may submit up to 10 minutes after the 70 minutes end.
Moodle will still accept submissions after the cutoff time, but it will be marked "late."
If this happens, you should email me ASAP and explain why you were late, and assert that you did not spend any more than 70 minutes working on the exam.

Summary:

time	description
09:00	Zoom opens, PDF of exam questions available on Moodle, you may start working
09:10	class/exam officially starts
10:00	class/exam officially ends
10:10	flex time ends, you must stop working
10:20	deadline for submitting to Moodle

Proctoring:

Please turn on your camera but mute your microphone.
During the exam, don't unmute to talk to me: you will end up talking to everyone else as well.
If you need to contact me, you can send me a message privately via the "chat" function in the Zoom meeting.
Aim the camera at you, not your desk; don't hold up your work for others to see.
Disconnect from the meeting after you've finished scanning and submitting to Moodle.

Tips:

Label your questions clearly, especially if you are doing things out of order (try not to).
Show your work.
Do not write in columns.
Even though you are under time pressure, try to write legibly; if I can't read your handwriting, I can't give you credit.
Make sure your scan is legible. If I can't open your PDF or read your content, I can't give you credit.
After submitting, download the PDF from Moodle and open it up to make sure you submitted the right file and it contains all the pages.
