Cheating and/or plagiarism:
If you are caught cheating on any
lab report or quiz
, the
minimum
penalty is a grade
of
0
for that report/quiz.
If you are caught cheating on an
exam
, you will be assigned a grade of
F
for the course.
In either case, a letter describing your offense will also be placed in your student file.
Repeated offenses
trigger progressively more severe forms of discipline.
Two
letters
result in
suspension or expulsion
from the University.
COPYING HOMEWORK
IS CHEATING
.
If you are caught cheating on your
homework, the
minimum
penalty is a grade of 0 for
ALL
homework in the course. A
letter
describing your offense will also be placed in your student file.
STUDENTS WHO CHEAT CHEAT THEIR FELLOW STUDENTS
.
If you see someone
cheating during an exam, inform the instructor in the following way.
Write a message on
your exam paper indicating what is happening and where.
Put your hand up, and the
instructor will come over.
Point out your note, and the instructor will take it from there.
This includes situations where someone may be cheating off you.
If you allow someone to
look at your work, you are also at fault and you will be disciplined.
Recognize that it is
often pointless to report cheating after the event.
