Homework + Quiz Homework problems will be posted weekly. Solution will be posted 3 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. Unless you have a university excuse (see Absences in the syllabus), late assignments will not be accepted for credit. Please do not ask for exceptions.

8
Exams Two 100-minutes evening examinations and a two- hour 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). No other resources are permitted in the exams.

9
Regrading Request for regrading an exam or homework/quiz must be done within one week after the exam or homework/quiz is returned. Your exams will be graded by the instructor while homework assignments and quizzes will be graded by the TA.

Grade Grading Policy: Homework5% Quiz 20% Exam 120% Exam 2 25% Final Exam 30% 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, class participation and quizzes are 25% of your total grade – please do not neglect this work.

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