The department does not have homework grader anymore. However, homework is important to learn the materials and will make up 10% of your final grade. We will check your homework  every two weeks. The students are divided into two groups according to their last names. The group A is made up from those people whose last name start from A-J. The rest of students are in group B. Each week, one group students  turn in their homework on Monday in class.  The homework has to follow the specific format. Otherwise, it may not be counted to full credit. Homework solution will be posted. If you do reasonabally well, you will get full credit. Some problems (around 50%) will be on your tests.
