No make-up exams will be given and no late homework will be accepted. Cheating on an exam results in 0 points for that exam, as well as further disciplinary action. Please read very carefully the following ACADEMIC INTEGRITY GUIDELINES.

GRADING POLICY

Midterm: 30%; Final Exam: 40%; Homework: 20%; Lecture attendance: 10%. The grading will be done on a curve, the median corresponding to a B-/C+.

CLASSROOM CONDUCT EXPECTATIONS

Lecture attendance is mandatory.

Electronic devices: The use of electronic devices (such as cell phones, laptops, tablets, iPods) for non-class-related matters while in class/section is not allowed. No visual or audio recording is allowed in class/section without prior permission of the instructor (whether by camera, cell phone, or other means).

Conversations: Please avoid having private conversations with your classmates during lecture and office hours.

E-mail etiquette: I will not discuss mathematics (e.g. solutions or hints of solutions to HW problems) via email. Office hours and lectures are the best venue for that purpose. However, if you have any type of administrative questions regarding this class, please do not hesitate to send me short and to the point email messages.

IMPORTANT: The weekly HW assignments will be posted in CANVAS.

GETTING HELP

Help with mathematical problems:

Section: Ask questions in section --- this is one of the main reasons why sections exist.
Office Hours: You are strongly advised to take full advantage of your professor's and ta's office hours.
Classmates: Sometimes a classmate can help. Sometimes you can learn by working out problems together with your classmates.

Help with personal problems which affect your class work:

Talk to the professor or, if appropriate, your college provost.
