Homework Assignments
 Homework assignments will be assigned and collected each week. The tentative due date is on Tuesday in class.
 The homework is not pledged. You are encouraged to discuss the problems. However each student is responsible for the final preparation of his/her own homework papers.
 Last update: 11/24, Homework 13 is available, due on Thursday 12/3 in class.

Exams
 There will be one midterm exam and one final exam (at the end of semester).
 The midterm exam is a 2hour exam with a total of 110 points. You can also choose to finish it in 3 hours. If so, 10 Points will be deducted, and the total will be 100 points. You can use the textbook, your own lecture notes and your own homework assignments during the exam. Other communications and helps are not allowed. You should spend no more than 2 consecutive hours on the exam.
 The final exam is a 3hour exam with a total of 110 points. You can also choose to finish it in 4 hours. If so, 10 Points will be deducted, and the total will be 100 points. You can use the textbook, your own lecture notes and your own homework assignments during the exam. Other communications and helps are not allowed. You should spend no more than 3 (or 4) consecutive hours on the exam. Please submit your exam to my office on Monday December 7th, between 10am12pm, 2pm4pm.
 Exams are under honor code. Be sure and hand in all the work you do on each problem. Good luck!
 Last update: 12/14, the solution for final exam is available.
