Civility in the Classroom: Students are expected to assist in maintaining a classroom environment which
is conducive to learning. In order to assure that all students have an opportunity to gain from time spent in
class troublesome behavior will not be tolerated. At a minimum, this includes using cellular phones,
making offensive remarks, reading newspapers, sleeping or engaging in any other form of distraction.

quizzes and 3 take-home computer projects based on the Homework Assignments. The lowest three scores
out of the 12 scores will be dropped and the remaining scores will be worth 20 of the final grade.
Tests: There will be three midterms and a Comprehensive final. For each test you need to bring an orange
scantron sheet, pencils and a calculator. Each of the tests will be worth 20.
Make-up Exams and Quizzes: Requests for make-ups will be granted ONLY when accompanied by a
letter from an appropriate university official, i.e. the Dean of Students. In all other cases, no make-up will
be given, and the procedures outlined in this syllabus will be followed. There are no exceptions to this
rule.
