Attendance: In order to learn mathematics, it is necessary to

50; Quizzes 50; Exam I 100; Exam II 100; Final Exam
150; Total 450
Homework: Weekly homework will be assigned on each Friday and
due the next Friday. This homework will be due by class time the Friday after
it is assigned. No late homework will be accepted! The solutions to every problem are to be written in
a clear, concise, and coherent manner. Solutions not clearly explained will not
be given full credit, even if the "answer" is correct.
Quizzes: Quizzes will usually be unannounced and will usually be 5 problems to
be solved in 20 minutes. There will be totally 8 quizzes throughout the whole
semester. Your best 5 grades will be counted towards the final grades. No
make-up quiz!
Exams: Two 75-minute evening examinations will be given during the semester and
a comprehensive final examination will be given during the final examination
period. NO books, notes, or calculators may be used on the examinations! You must bring your University ID card to all
