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

Use of cell phones (in any manner), laptops, smartphones, tablets and

Chatting with neighbours, even when whispered, is equally

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.
