CS4240: Exam 3 Info
This document last updated on Weds., Dec. 7, at 3:29 1/2 pm.
The test will be given as take-home exam. The instructor will
explain how to get it, and you must turn it in to him or to the CS
office in OLS 204 before Monday, Dec. 13, at 4:30pm. (The CS
office is open M-F, normal business hours.)
The Honor code will apply to Exam 3 as follows. You will take it
exactly as if it were being given in class: no books, notes, Web
access, friends, etc. You cannot talk to other students about it
until after everyone has taken it. You will time yourself and use
no more than the time limit (which will be more than enough to complete
it). We expect you to follow these rules, and the Honor
Code is what allows us to do this instead of having everyone stick
around until the last day of the exam period.
