Grading Policies:
Homeworks can be discussed collaboratively,
but each person must turn in their own
solutions with unique writeup/analysis.
Collaborative means talking with each other
about approaches, techniques, etc.
Collaborative does not mean sitting
side-by-side working out the answers, or
swapping final solutions to copy!
Homework will be accepted in hardcopy form
only -- no electronic/email submissions.
Assignments are due at 4:00pm on the due date
unless otherwise noted.
Late HW policy: You get one free late homework
(up to one week late), no
questions asked. After that, it's a penalty of
20% for every day late, unless you have an
prearranged, excused reason.
Missed test policy: Don't miss tests.
If you are ill or have some other critical
reason for missing a test, you must let me
know in advance of the test, and
document the reason.
