ACADEMIC CONDUCT ISSUES

• Important:

• Do not copy, paraphrase or translate anything from anywhere without saying from where you obtained it. Source: http://provost.concordia.ca/academicintegrity/plagiarism

It is not OK

• Copy from ANYWHERE without saying from where it came. • Let another student copy your work and then submit it as his/her own. • Hand in the same assignment in more than one class. • Have unauthorized material in an exam, such as cheat sheets, crib notes.

YOU DON'T HAVE TO BE CAUGHT USING THEM - JUST HAVING THEM WILL GET YOU INTO TROUBLE!

• Copy from someone else's exam. • Communicate with another student during an exam by talking or using

some form of signals. • Add or remove pages from an examination booklet or take the booklet out

of an exam room. • Get hold of or steal exam or assignment answers or questions. • Write a test or exam for someone else or have someone write for you. • Hand in false documents such as medical notes, transcript or record. • Falsify data or research results.

But if you do...

•The Professor will file an incident report.

•You will be asked to come to an interview with the Associate Dean.

•A decision will be made to uphold or dismiss the charge.

•A grade of "0" in the assignment, exam or course

•A failing grade in the course with no right to a supplemental exam

•Requirement to take up to an additional 24 credits

•In the case of a second offence:

•Suspension of up to three years

•Expulsion from the University

•A charge of academic misconduct will appear on your student record.

Final Evaluation Note

• The final exam will be marked and grades submitted according to the academic requirements of the University.

• It is reasonable for students who think that they performed better than their grade, the final exam.

• However, retrieving exams is a time consuming activity. This is why the final exams will be seen on a scheduled date . After the beginning of the summer term, the instructor will post on his office door the scheduled day for exam review.

• If one is interested, he/she must pass by and book a time slot of 10 minutes.

• The objectives of this review are to provide the opportunity for the student to assess his mistakes.

• Meanwhile, the review might help the student to evaluate if he/she will apply for the exam re-evaluation.

• The review period will be not used, under any circumstance to negotiate or comment on the grade. As the review day will have 20 such slots, the exam review will be based on first-come first-served basis.

• This information and other updates relating to the course will be posted on the course Moodle page.
