CS173: Exam instructions

The following are standard instructions for CS 173 examlets. Please familiarize yourself with them ahead of the first exam. See this information about how to make up missed examlets, and also this information about disabilties and other special situations.

Time and location

Examlets will be given in class Monday or Tuesday (depending on which lecture you are in). Unless you have made a special arrangement ahead of time, you must go to the lecture you are registered for. We need to do an override on moodle to let you take it at a different time.

The exam itself will be posted on moodle. Proctoring will be on zoom.

Zoom links can be found on our course home page. Get into your breakout room on zoom before starting the exam on moodle. At the end, submit on moodle before leaving the zoom class.

After you enter zoom, watch for an invitation to join a breakout room.

Getting ready

This exam will be proctored on zoom. Before taking the exam arrange your zoom camera so that it can see your entire workspace (your face, keyboard, scratch paper, screen). If you don't have a movable webcam, you can install the zoom app onto your cell phone. Here are some hints on how to position your camera.

To take the exam, you must be logged in to zoom using your U. Illinois (netID) credentials. Ahead of time, go to U. Illinois zoom and make sure that your display name is correct.

Use Chrome or Firefox; Safari is known to have incompatibilities with moodle.

Starting your exam

Go to moodle and click on the exam. If the exam is not visible or will not let you open it, pop out of your breakout room and consult with the instructor.

General rules

You have 40 minutes to do the exam, starting from when you open it. (Watch the timer on moodle.)

This is a closed-book exam: no books, no notes, no looking on the internet, no consulting other people (e.g. friends). Scratch paper is ok, but it must start off blank.

Electronic devices other than your computer and web camera must be turned off or put where you cannot see/use them. Your cell phone can only be used to connect to the zoom session. You do not need, and should not use, a calculator.

Foam earplugs are ok, but headphones and earbuds are not allowed.

For open-answer questions, your answer must be typed directly into the answer box. You cannot upload scans of handwritten work. Cut and paste from other editing windows may be possible but can result in messed-up formatting or cause the exam window to lock up.

If you lose internet connectivity, your window freezes, or the like, reboot as needed, re-enter the zoom call and click again on the exam as soon as possible. Moodle autosaves your work frequently, so you should be able to pick up where you left off. Briefly explain what happened in the box on the exam for reporting problems.

Similarly, moodle will autosubmit your work if you run out the clock without pushing the submit button.

Doing the exam

Points may be deducted for solutions which are correct, but hard to understand, poorly explained, excessively hard to read, or excessively complicated. Use your best mathematical style.

Open-answer questions asking for a short factual answer normally also require brief justification or work. Provide this unless there are clear indications to the contrary, e.g. the question is worth only a couple points. You can lose significant points for a short answer with no justification. You can also lose points for leading up to the final conclusion but never actually stating it.

Unless explicitly requested by the problem, it is not necessary to simplify or calculate out complex constant expressions such as 0.715 or 7! or log3 2. However, you should simplify expressions such as logarithms inside exponents (e.g. 3log2 n).

Use whitespace to make your math easy to read, e.g. use paragraphs and linebreaks, do not make any individual equation very long.

Academic integrity issues

You may not leave the view of the proctor for a significant length of time and then come back and continue working on your exam. If an emergency (e.g. upset stomach) forces you to leave before you have had time to finish, stop working on the exam and email a full explanation to your instructor. We'll schedule you to take a makeup. Very brief interruptions (e.g. to answer a knock at the door of your room) are ok. This rule doesn't apply to the final exam.

Similarly, if you start an exam but discover you are too sick to continue, we'll abort the exam and have you do a makeup. Tell the proctor at the time. Then email a full explanation to your instrutor.

If possible, you should be the only person in the room while you are taking the exam. If someone else must be in the room, e.g. a dorm roommate, do your best to act as if they are not there.

Obviously, you may not look at the exams of other students, share answers, and so forth. But, also, do not do things which look like cheating. If you have to do something that could be misinterpreted, e.g. your phone rings, deal with it quickly and (if it's not obvious) tell the tell the proctor what is going on.
