Working together and academic integrity
Homework: We have no objection to collaboration on the homework,
that it is done in a way that maximizes the benefit of the homework to
all people involved. It is our experience that you
- maximum benefit from a homework problem if you work hard on it
before combining your ideas with someone else's,
Regardless of whether you arrive at solutions in collaboration with

Integrity Code. We take academic

sample of exam books before returning them.
Use of cell phones (in any manner), laptops, smartphones, tablets and
other electronic devices during class is highly inappropriate, as it is
distracting and disrespectful to fellow students and the instructor.
Chatting with neighbours, even when whispered, is equally
inappropriate. If you have a question then please ask the instructor so
the whole class may benefit too.
Arriving late and leaving early is also discouraged. If it happens then
please enter/leave the room silently and do not disrupt the other
students or instructor. Thank you.
