Late Work
•
Unless otherwise stated, all work (homeworks)
and assessments (exams, quizzes, presentations)
must be complete, and handed in/ready-to-go, at the
beginning of class.
• For work that is handed in, it will be accepted later
that same day, with a 10% point penalty, only if you
secure the instructor's permission (verbally or in
writing) first
– In other words, make sure you talk to the instructor
before you assume that you can hand it in late.
• Work will not be accepted past the day that it's due.

Late Work
• All late work should be handed in
to room 154, where they will stamp
it with the time that it was handed
in at.
• Homework will not be accepted if
it's handed in anywhere else, or
handed into room 154 WITHOUT a
time-stamp.

Exam
• Calculators can do most of what
you’re required to do
• Therefore, showing only an answer
(even a correct one) will get 0
points on the exam/homework
• You must show all work, to
demonstrate that you know what’s
going on, for full credit.

• Your calculator’s memory WILL be
reset immediately before the exam
• Save anything you want to keep prior to the
exam!

Exam Ideas
• These ideas aren’t necessarily what will
happen
• They’re good to start thinking about.
• Each problem is given, and so is the
answer, and your job is to fill in the
work in between.
• Cheatsheet/crib card: Let’s decide this
later, but for now, practice assuming
that you won’t have one.
