Laboratory experiments may not be made up because of the difficulties and safety hazards presented by trying to maintain the equipment and chemicals from previous laboratories. Students, whose absence was for one of the three reasons given in the catalog and who present a valid written excuse, may be excused by the instructor. In these cases the student will receive the average grade of all their other laboratories in place of the absence. In no case can this practice excuse more than a quarter of the laboratories. Students will not be allowed to make up homework quizzes for any reason.
Help is always available.
Come to my office in 304a Stevens Hall during scheduled office hours, which are posted on the web site for this course, or make an appointment for another time. The best times to catch me to make an appointment are after any lecture. You may also e-mail to the professor. Because of the speed with which some of the topics will be covered in this course, it is to your advantage to seek immediate help if you do not understand. Do not wait until the test to admit that you are having difficulty.
