General remarks

1. Homework must be legible and reasonably neat, and pages must be fastened with a staple or paperclip.
2. You should start attempting the problems as soon as possible after the material is presented in lecture. Please don't save it all for Sunday night.
The assigned problems represent what we expect the ``typical'' student to need in order to learn the material. Many of you will want to do more for extra practice. There are plenty of unassigned problems that you can try. Notice that the odd-numbered problems usually have answers in the back of the book .
3. If you get stuck on a problem, look for a similar problem with an answer in the back or a solution in the study guide.  
4. For extra practice, especially around exam time, the study guide has sample test questions (with solutions) at the end of each chapter and several sample tests (with solutions) at the end of the book. These sample tests often do the same thing we try to do on quizzes and prelims; namely, test to see if you understand the ideas. Thus many of the problems are not simply carbon copies of homework problems.
