The following are standard instructions for CS 173 (Lecture A) midterms and final exam. Please familiarize yourself with them ahead of the first exam.

Please feel free to ask the proctors for help with problems created by disabilities or by other circumstances unrelated to the exam content.

We'll use the front screen or board to post the ending time, turn-in instructions, bug fixes, and clarifications. If your vision is poor, please sit towards the front.

All exams are closed-book exams. You may not consult with other students. You may not use notes. All electronic devices (including your cell phone and calculator) must be turned off and out of reach (e.g., in your bag under the table). Watches are ok, as long as they are simple timekeeping devices.

Please bring any apparent bugs or ambiguity to the attention of the proctors.

Make sure your name, netID, and discussion section are clearly written on the exam. If the exam has separate parts (e.g., two separate sheets) or you used extra paper or the final page seems loose, make sure this information is on each separate part.

If possible, do not sit next to any other student. More generally, if we assign you to a seat, do not find another seat.

Do all work in the space provided, using the backs of sheets if necessary. Please indicate clearly if your work continues onto the back side, or if your work needs to be read in some non-obvious order. See the proctor if you need more paper.

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

Do not erase your work. There are two reasons for this advice. First, partial credit will be given where possible - and all too often students erase correct material and replace it with incorrect material. Second, it is often difficult to read what is written on top of erased material.

Brief explanations and/or showing work (even when not requested by the problem) may increase partial credit for buggy answers. However, we will not provide partial credit for multiple-choice questions. Therefore, there is no need to provide explanations or justifications for multiple choice questions.

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.

If you wish to discuss the exam with other students after it is over, you must first verify that they have already taken the exam, e.g., they aren't about to take a makeup exam.
