(*) stands for an optional problem.

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.

Have a great semester!
