Important Notice on Academic Ethics:

Cheating is wrong. Cheating hurts our community by undermining academic integrity, creating mistrust, and fostering unfair competition. The university will punish cheaters with failure on an assignment, failure in a course, permanent transcript notation, suspension, and/or expulsion. Offenses may be reported to medical, law or other professional or graduate schools when a cheater applies. Violations can include cheating on exams, plagiarism, use of homework solutions obtained from outside the course materials provided, improper use of the Internet and electronic devices, unauthorized collaboration, alteration of graded assignments, forgery and falsification, lying, facilitating academic dishonesty, and unfair competition. Ignorance of these rules is not an excuse.

In this course, all work is INDIVIDUAL (homework, midterm exams, final exam), except for the execution of the laboratories and the preparation of the laboratory reports. You may of course also join with other students in studying for exams, solving problems and discussing exercises (other than those assigned as homework) together. If you have questions about this policy, please ask the instructor. Old exams from this course may be found at the course webpage. For more information, see the guide on "Academic Ethics for Undergraduates" and the Ethics Board web site (http://ethics.jhu.edu).
