solutions
is
your
sole

responsibility.


-

No assignments submitted via WebCT are accepted
.


-

Late due assignments are generally
NOT

accepted.


-

A late due assignment may receive up to 70% of the actual credits earned on this assignment with a

rea
sonable excuse, which is subject to the instructor's judgment.


-

Solutions will be posted on the course homepage (WebCT).


-

No assignments are accepted

Exam problems are derived from your reading assignments, class notes and hom
ework assignments.
Study and review of these materials before the exam will help you to crash the exam.


-

Please be advised that there
will be NO ti me for you to dig in the book for solutions

during the final
exam
, because the exam is well designed for a

full
working load of 100 minutes solely in solving problems.
The open book is for you to
refer to equations, charts and tables
i
n the book i
n assistance to solving
problems.


-

No make
-
up exam will be granted unless:

1.

A student

is deeply sick on the day

of exam with a doctor's written proof; or
