Grading Policy:
Two
lowest homework grades will be dropped. The course grade will then be
computed as follows: Homework & Quizzes 20%, Hour-exams 30%, Final
50%. The grades might be curved with a scale depending on the
performance of the class. Letter grades will then be assigned according
to the scale:
A, 100-90; B,
89-80; C,
79-70; D, 69-60; F, below 59.
However, you must
get at
least 60% on the final to
pass this course with C.

Homework will be
assigned in class, and collected every Friday
at the beginning of the class. Late homework will be not accepted. It
