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.
Homework and Quizzes: Homework will be assigned daily. There will be 9 in-class multiple choice
quizzes and 3 take-home quizzes (computer projects) based on the Homework Assignments. The lowest
three quizzes will be dropped and the quizzes will be worth 20%.
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.
