• It is encouraged to read the sections in the book after each lecture, as the lecture notes may differ slightly from the text and reading the book after the lecture helps you understand.
• Homeworks will be posted at the beginning of each week. For example, Homework 1 will be posted before 09/28, homework 2 will be posted before 10/02, etc.
• Homeworks will not be collected. Instead, homework problems will be chosen from odd numbered exercises in the textbook, so you can check the answers yourself. If you have any doubt, come to office hours.
• Detailed solution will be provided for 5 problems of each homework. You vote for the problem in the current homework that troubles you the most, and the 5 problems with highest votes will be chosen.
• Each quiz will contain one problem that is picked from the homework with the same number. For example, the problem in Quiz 3 will be the same to a problem in homework 3. The 3 problems with solutions provided will not be picked. The later Quiz among the two will be slightly harder.
• Quizzes can only be taken in the section you are assigned, unless permitted by the instructor. Otherwise no credit for the quiz taken in the wrong section. You need to contact the instructor at least one day in advance to get permission. Graded quizzes will be returned in the following week. Quiz 9 will be kept in the TA's offices for pick up before the final.
• The problems in the midterm and the final will be taken from, or almost identical to, homework problems.
• In all the quizzes and exams, you need to write down all the steps that lead to your answer to get full credit.
• The quizzes and exams are close book. No electronic devices are allowed. In the midterm and the final (but not the quizzes) you can bring an ${5}^{\text{'}}x{8}^{\text{'}}$ index card written on both sides.
• Please remember to bring a picture ID to all the quizzes and exams and make it visiable. It may be checked.

• my.ucla.edu will be used.
• The lowest score among Quizzes 1--9 will be dropped.
• Two schemes will be used.

1. Quizzes: 20%; Midterm: 40%; Final: 40%.
2. Quizzes: 20%; Final: 80%.

The final grade will be the higher one from the two methods.

• There will be no make-up of the midterm under any circumstances.
• If you cannot take the final, talk to me before the midterm. However I cannot guarantee an early final.
• The final will cover all the materials. With about 50% points on materials before the midterm, and 50% for materials after the midterm.
• The grade "incomplete" will only be given in very special cases, when a student

• is doing well in the course, and
• cannot take the final for a very serious and documented reason, and
• contacts the instructor before the final.
