Safety Protocols

• For updated information on safety protocols in the classroom, see here, here and here.
• If you are feeling sick, do NOT come to class. Follow the quarantine/testing protocols in the above links.
• In class, everyone must be wearing a face mask, such as a cloth mask, surgical mask, or N95 mask. A plastic face shield is NOT a face mask. If you are not wearing a face mask, you should not be in the classroom.
• Eating food is NOT allowed during class.
• There is a zoom link posted on blackboard in case hybrid teaching (a classroom lecture with camera/microphone) becomes necessary.  The classroom is equipped with a camera/microphone, and I will try to get them working the first week of class.

Email Policy:

• My email address for this course is stevenmheilman@gmail.com
• It is your responsibility to make sure you are receiving emails from stevenmheilman@gmail.com , and they are not being sent to your spam folder.
• Do NOT email me with questions that can be answered from this syllabus.

Exam Procedures: Students must bring their USCID cards to the midterms and to the final exam. Phones must be turned off. Cheating on an exam results in a score of zero on that exam. Exams can be regraded at most 15 days after the date of the exam. This policy extends to homeworks as well. All students are expected to be familiar with the USC Student Conduct Code. (See also here.)
Accessibility Services: If you are registered with accessibility services, I would be happy to discuss this at the beginning of the course. Any student requesting accommodations based on a disability is required to register with Accessibility Services (OSAS) each semester. A letter of verification for approved accommodations can be obtained from OSAS. Please be sure the letter is delivered to me as early in the semester as possible. OSAS is located in 301 STU and is open 8:30am-5:00pm, Monday through Friday.

Discrimination, sexual assault, and harassment are not tolerated by the university. You are encouraged to report any incidents to the Office of Equity and Diversity http://equity.usc.edu/ or to the Department of Public Safety http://capsnet.usc.edu/department/department-public-safety/online-forms/contact-us. This is important for the safety whole USC community. Another member of the university community - such as a friend, classmate, advisor, or faculty member - can help initiate the report, or can initiate the report on behalf of another person. The Center for Women and Men http://www.usc.edu/student-affairs/cwm/ provides 24/7 confidential support, and the sexual assault resource center webpage sarc@usc.edu describes reporting options and other resources.

Exam Resources: Some past 408 exams appear here, near the bottom of the page. Some practice exams for a course similar to ours appear here, here, and here

Homework Policy:

• Homeworks are due at 12PM noon Thursdays, i.e. at the beginning of the first discussion session on Thursdays.
• Homeworks are submitted in blackboard, under the "Assignments" tab. You are allowed unlimited submission "attempts" for an assignment, but only the last submission will be graded. To avoid internet issues, I recommend making your first submission of an assignment well in advance of the deadline.
• Homeworks should be submitted as single PDF documents. One way to create a PDF document from paper homework assignments is the freely available Adode Scan App
• Late homework is not accepted.
• If you still want to turn in your homework late, then the number of minutes late divided by ten will be deducted from the homework score.  The exact deduction and rounding procedure is not guaranteed to be accurate.
• The single lowest homework score will be dropped. This policy is meant to account for illnesses, emergencies, dropped internet connections, etc.
• You may not use the internet to try to find answers to homework problems.
• Do not submit homework via email.
• Collaboration on homeworks is allowed and encouraged.
• All homework assignments must be written by you, i.e. you cannot copy someone else`s solution verbatim.

Quiz Policy

• There will be several quizzes throughout the semester, as listed in the schedule below, roughly every other week. One week before the quiz occurs, a list of quiz problems will be posted on the course website. The quiz will have a few problems similar or identical to the posted list of problems.
• The single lowest quiz score will be dropped. This policy is meant to account for illnesses, emergencies, etc.
• Quizzes will be administered in your discussion section on Thursday. Each quiz should last about 10-15 minutes.
• No notes, no books, no calculators, etc. will be allowed during the quizzes.

• The final course grade is weighted as the larger of the following two schemes.
• Scheme 1: class participation (3%), homework (11%), quizzes (11%), the first midterm (20%), the second midterm (20%), and the final (35%).
• Scheme 2: class participation (3%), homework (11%), quizzes (11%), the largest midterm grade (30%), and the final (45%).
The grade for the semester will be curved. However, I do not "curve down" since anyone who exceeds my expectations in the class by showing A-level performance on the exams and homeworks will receive an A for the class.
• If you cannot attend one of the exams, you must notify me within the first two weeks of the start of the quarter. Later requests for rescheduling will most likely be denied.
• Class participation is not the same as attendance.  I will never explicitly take attendance, but I will notice if someone is frequently absent.  Things that increase your class participation grade include: asking good questions, paying attention in class, showing up on time or early to class, etc. Things that decrease your class participation grade include: excessive talking or disruptions during class, frequent absences, excessive texting/smartphone usage in class, frequent tardiness, etc.
• You must take the final exam to pass the course.

Tentative Schedule: (This schedule may change slightly during the course.)

Advice on succeeding in a math class:

• Review the relevant course material before you come to lecture. Consider reviewing course material a week or two before the semester starts.
• When reading mathematics, use a pencil and paper to sketch the calculations that are performed by the author.
• Come to class with questions, so you can get more out of the lecture. Also, finish your homework at least two days before it is due, to alleviate deadline stress.
• Write a rough draft and a separate final draft for your homework. This procedure will help you catch mistakes.
• If you are having difficulty with the material or a particular homework problem, review Polya's Problem Solving Strategies, and come to office hours.
