Grades will be based on homework, quizzes, two 1-hour tests, and a final exam (scheduled by the registrar for this time block), weighted as follows:

 Two midterm exams, in class, dates TBA 40% The final exam, as scheduled by registrar 40% Quizzes, once every 1-2 weeks 10% Graded homework 10%

The dates of the midterm exams and quizzes will be announced in advance. Each quiz will take 15-20 min. Homework is assigned once a week and is due the following week. You may discuss the homework problems with other students in the class; however, if you do, you should write on your homework submission the students with whom you discussed the assignment. (You do not need to mention any help you received from the TA's or instructor.) You may not copy the written work of another student or allow another student to copy your written work. What you submit should be your own work. Late homework will not be accepted. Students who miss a quiz (or exam) will not be granted a make-up quiz (or exam) unless there is a documented medical or other emergencies. .

If you are a student who needs academic accommodations because of a documented disability, please contact me and present your letter of accommodation as soon as possible. If you have questions about documenting a disability or requesting academic accommodations, you should contact Beth Rodgers-Kay in Academic Services (x6-3470 or brodgers@brandeis.edu). Letters of accommodation should be presented at the start of the semester to ensure provision of accommodations. Accommodations cannot be granted retroactively.

You are expected to follow the University's policy on academic integrity, which is distributed annually as section 4 of the Rights and Responsibilities Handbook. Instances of alleged dishonesty will be forwarded to the Department of Student Development and Conduct for possible referral to the Student Judicial System. Potential sanctions include failure in the course and suspension from the University. If you have any questions about how these policies apply to your conduct in this course, please ask.
