Grading: Grades in this class will be computed from homework (see below), two in-class midterms, and a final exam. Your grade will be whichever of the two numbers below are higher:
Homework: Homework in this class will be online, through the WeBWork system. One assignment will be posted each week, due the following week as noted on the lecture schedule. Your lowest homework grade will be dropped at the end of the semester.
  1. You may attempt each question as often as you like until you solve the problem. There is no penalty for a wrong answer. This is to help you correct your own mistakes, and to get instant feedback on your attempts.
  2. The questions are generated randomly, and the numbers are different for each student.
  3. Please try to do the problems by yourself, and without the use of other calculators or software. Since calculators and software are not allowed in the exams, you should practice working without them.
  4. If you really get stuck, you can request help by clicking the email instructor button. However, it may take some time to get a response, so please don't wait till the last minute.
  5. In general, its a good idea to start the assignments early rather than waiting till the last minute. The deadlines are enforced by the system, and it will shut down automatically when time is up, so give yourself plenty of extra time in case of problems.
Note that the textbook also has many practice problems with answers in the back. It is recommended that you try all these problems, so that you may track your understanding.
