How to do well in this class? The answer is straightforward and old-fashioned: Prepare for Class, Keep Up, and Do the Homework Problems. The exams will contain at least 80% from material covered in lecturs and homework problems, with little modification. A sure way to get a good grade is to study for the class, and do the assignments as if you are taking the tests, without the help of the book, notes and computers. It also helps a great deal to ask questions during and after the lectures, especially after you have already previewed the material.

Instructor's comments: The goal of this class is to have students learn the material well and then to give them fair and accurate grades. To achieve this goal, the instructor belives in serious homework problems and hard exams. Serious problems make students learn more and better. Hard exams give a better evaluation of students' learning. In other words, if you are taking this class just to get a passing grade and with no intention to learn, consider taking another class.
