Homework (20%) Homework is the most important part of this course. Homework problems will be assigned during the semester on weekly basis. They will be graded. After an assignment has been turned in, the solutions to the problems will be posted below.

 

Assignments are due at the beginning of the class on the due date. Each student will be given one opportunity to hand in an assignment late for up to two days. After you have used up the two free late days, a penalty of 20% per day will be applied to each late assignment.


Quizzes (15%)
 Based on the homework assignments, 10 quizzes will be given at the beginning of the class on the dates specified on the tentative schedule. Each student will be given two opportunities to either make-up a missed quiz or retake a poor quiz during my office hours within one week after the quiz was given.


Midterm Exams (20%
X 2) Two midterm examinations are scheduled on the days specified on the tentative schedule. Student who are unable to attend an examination should contact the instructor as early as possible prior to the examination to discuss the possibility of alternate arrangements. A student who is absent from an examination may request a make-up examination only if the examination was missed for a serious reason (such as family emergency, or illness with a doctorís note).

 

Final Exam (25%) Final examination date and time is listed on the tentatitive schedule below. No make-up final.


Grading
 Course grades are determined by: A (90.0%-100%); B (80.0%-89.9%); C (70.0%-79.9%); D (60.0%-69.9%); F (<60.0%).
