Homework Your chance to practice using the concepts presented in class  Teamwork vs. Individual work?  Answers to even numbered problems are in the text 

Homework + Quiz Homework problems will be posted weekly, usually on Friday. Solutions will be posted 2 days before due day. Not all homework problems may be graded. A quiz will be given on each homework due day. Each quiz covers the homework assigned in the previous week with problems very similar or identical to the homework problems.

Exams Two 50-minutes in-class examinations and a twohour final examination are scheduled (see the course calendar given in the syllabus). Unexcused absences will result in a grade of zero for missed examinations. The exams are closed book. You are allowed to bring in one single-

sided letter size paper with your own notes and formulas (no examples and sample problems). This sheet will be turned in with your exam. No other resources are permitted in the exams.

Regrading Request for regrading an exam or homework/quiz must be done within one week after the exam, quiz, homework is returned. Your exams will be graded by the instructor. For exam grade reconsiderations, a written explanation must be presented for each problem to be re-examined. This must be limited to: a thorough explanation of your solution, its connection to the posted exam solution, and the reasons for the awarding of additional points.

Grade Grading Policy: Homework 5% Quizzes 20% Exam 1 20% Exam 2 20% Final Exam 35% Letter grades will be assigned from your total course score according to 90% to 100%: A; 80% to 89%: B; 70% to 79%: C; 60% to 69%: D; below 60%: F. Please note that homework and quizzes are 25% of your total grade – please do not neglect this work.

Attendance Policy  



Attendance is highly recommended Quizzes will be given on the assignment due days. It is your responsibility to make sure you attend class and take quizzes on those days. Only University excurse will be accepted for missing homework and quizzes. The instructor is under no obligation to provide an opportunity for the student to make up work missed because of an unexcused absence.
