Lab Policy Labs (programs) are due at the beginning of class on the first meeting of the weeks indicated above. Labs turned in 1 second after class begins, until the beginning of the next class, are one class day late, etc. Labs turned in late are discounted in score by 2-N where N is the number of class days late. Thus late labs are worth 1/2, 1/4, 1/8, ... credit. It is often better to turn in labs on time that are nearly correct than to turn them in late. Labs are to be done by each student individually. Labs may be turned in the class before they are due to avoid late penalties.

Homework is not accepted late.

CIS 575 students will be required to write a short (about 5 pages including illustrations) paper about a protocol (list provided later).
