Final Exam: Date to be announced Grading policy: Midterms = 20%, Homework = 20%, Final exam = 40%. Homework policy: 3 Homework assignments each week. Problems are assigned each class and are due at the beginning of the next class. It is OK to discuss the problems amongst yourselves - note the names of your coworkers somewhere on your assignment. However each student must hand in their own solutions that they have written themselves. (Copying someone else's homework is unacceptable.) To make the job of grading easier, could you please follow the following guidelines for homework: Write your name on your HW. Neat, legible handwriting. Write on one side of the paper only. The problems should be in the order assigned. Staple (or paper-clip) all pages together.
