Academic dishonesty will not be tolerated. Students are responsible for educating themselves and following the university honor code (http://www.shc.umd.edu/SHC/default.aspx)
No late homework will be accepted without arrangements made prior to due dates. Late homework will have reduced value (25% same day, 50% one day late). Students are encouraged to study and work together, but all solutions submitted should be your own in your own writing and using your own words.
If special accommodations are required due to disability, religious observances, or other, please contact the instructor in advance to make arrangements.
