Homework Homework will be due each Friday before the class. Late homework will not be accepted. A more difficult problem is given in each homework assignment. Doing this problem is required for 570 students, but optional for 470 students. Solutions are provided on Fridays.
Constructive collaboration is encouraged.
Collaboration is constructive only after you have worked on a problem long enough to have well-defined questions to ask of someone else and some ideas to contribute to others' questions. Copying is not constructive. 570 students are also required to do a more difficult problem in each homework assignment. If one cannot take a test due to any other reasons, you need to discuss with me before the test. A student who misses a test without a valid reason will be given a zero for that test.
