CSCI 243 Fall 2011 Exam #1
Directions: This exam is closed book,
closed notes, closed neighbor, closed computer, and (hopefully) open mind. Write legibly, since if I can’t decipher it,
I have to assume that it is wrong.
Maximize your score by looking over the whole test and then answering the
easy questions first. Good luck and have
fun!
