Grades will be computed as follows:

Two midterm exams, in class, dates TBA 30%
The final exam, as scheduled by registrar 40%
Quizzes, once every 1-2 weeks 15%
Graded homework 15%

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. Late homework will not be accepted and there will be no make-up quizzes. Other parameters, such as class participation (answering or asking questions in class) and bonus points (for optional problems or exceptionally thoughtful analysis of tests/homework) will also affect the students' performance.

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.

Good luck on the exam!
