INTERNET-BASED HELP: My email address is given above. You may contact me to ask a question, to report an expected absence from class, or for any other concerns you may have. Course information is available on my Web site. At the beginning of the semester everyone will be given a user ID and password to access their grades on line. THESE ARE YOUR OFFICIAL GRADES, and it is in your interest to make sure they are recorded accurately. To get your user ID and password, you need to send me an email at the above address. I will reply with your user ID and password. Your grades are protected behind both the college firewall and my fire- wall. In addition, I monitor all uses of the site and can identify any unauthorized attempt to access information.

OFFICE HOURS: My office hours are posted on my door. You are welcome to come by during those hours to discuss the course work and ask questions, and I encourage you to do so. Although I prefer you would observe the posted office hours, I am usually available around my office during the day whenever I am not in class in case my office hours are not convenient for you. You may always make an appointment if necessary.

GRADING: There will be 4 tests each worth a total of 45%, a comprehensive final exam counting 25%, quizzes on the homework worth 10%, and lab worth 20%. There will be no makeup exams or labs; however, the final exam grade will substitute for any missed test or lower test score. A student with an 85% average test score or higher may choose to skip the final and let the average score substitute for the final exam grade. A student who is exempt from the final may still take it to improve his or her grade if so desired. For such a student the 25% of the grade corresponding to the final exam will be the higher of the final exam grade and the average test score. This is to insure that no penalty is incurred by an exempt student electing to take the final. The two lowest lab grades (or missed labs) will be dropped as will the two lowest quiz scores. Number grades correspond to letter grades as follows: 90-100% = A, 80-90% = B, 70-80% = C, 60-70% = D.

EXAMS: Tests will be multiple choice and problems. Be sure to bring a working calculator to the tests. A sheet of equations will be handed out for use with the tests. You should study the review questions at the end of each chapter to prepare for the multiple choice portion. The correct physical units are required in the problem answers for full credit. All tests except the final will be administered in the Testing Center. The final exam will be taken in the classroom.

QUIZZES: Quizzes will be administered over the homework material according to the schedule above. There will be four multiple-choice questions and one or two problems chosen from the homework on each quiz. These problems will be exactly like the corresponding homework problems except that the numbers used in the calculations will usually be different. You are allowed to work the quizzes using your completed homework, and you should be sure to bring it with you on the day of the quiz since only 12 minutes will typically be alloted for the quiz. No other materials are allowed.

MISCELLANEOUS: Students are expected to show up on time for class. Students are also expected to be courteous to me and the other students. For example, if you arrive late or must leave the class temporarily, do so quietly. If you must leave early for any reason, please inform me ahead of time. In particular, if you need to leave a lab early, it must be with the knowledge and consent of both myself and your lab partners. I reserve the right to penalize a student for noncompliance with these requests. If you are going to be absent for more than one class period for any reason, be sure to let me know ahead of time if possible. I will be taking attendance and following the college policy. You may be dropped after six absences. Two tardies equals an absence.
