    • Test 1: 17.5 percent
    • Test 2: 17.5 percent
    • Final Exam: 30 percent

    • B: 80 percent (or better)
    • C: 70 percent (or better)
    • D: 60 percent (or better)
  • Policies: Attendance is required and contributes to the final grade. Three classes may be missed without affecting this grade. A student who was absent in more than half of the class meetings automatically has failed the course, regardless of his other scores.

    The daily homework assignment will consist of a reading assignment and a problem assignment. Part of the daily problem assignment has to be completed online via the MyMathLab system of Pearson Education, available at the web page under the course id sommerhaeuser68245. The time frame for this completion begins after the lecture in which the problem was assigned and ends one hour before the next lecture. A student who has attempted less than half of the online homework problems automatically has failed the course, regardless of his other scores. The homework problems and the textbook examples that appear in the reading assignment form the basis for the quiz problems and the test problems.

    Every week, there will be a short quiz. No make-up quizzes will be offered. However, the two lowest quiz grades will be dropped.

    Eating, drinking, and smoking is not permitted in the classroom. The use of electronic devices such as laptops, i-pods, cellphones, or calculators is not allowed unless explicitly stated by the professor. Cellphones may be brought to class, but must be completely off and stowed away. They must not be used during class at any time.
