Assignments: Homework will be assigned almost every
class period and will be collected once a week. On the date due, homework must
be turned in at the start of class, or within 10 minutes thereof for students
arriving late. No other late homework will be accepted, except under
extreme circumstances. 
Students may work together on homework problems,
but of course an act of copying another student's solution without making
a substantial contribution to the solution process is plagiarism.
Each student must complete the writing of his or her own homework, no
photocopied work of another person will be allowed. Along with the
individual student's name, on the top front page of homework turned in,
must also appear the names of other students who assisted with the
solutions.


Relative to assignments in general, students should attempt
to read assigned material before coming to class. After coming to class,
they should attempt the assigned homework. Students should expect quizzes
to be given at times in class. (They will NOT be
pre-announced.)




Late homeworks: 
No late homework will be accepted (even with a doctor's note, and even in
the same day). There will be no exception (even for those who enrolled 
this class late). 
Instead, the two lowest scores will be thrown out in the computation of the final average in this category.




Exams: The exam schedules are:
         Exam 1:  Thu Feb 16  in class
         Exam 2:  Tue Mar 27  in class     
         Exam 3:  Tue Apr 24  in class     
     Final Exam:  Mon May  8  8:00 AM - 10:00 AM (in class)


Evaluation: I am expecting that every week there
will either be some assignments and/or quizzes submitted for grading or
an examination will be given.
There will be three in-class hour examinations
and a two-hour comprehensive final examination. The point basis for
the final course grade will be as indicated below. The actual grade
will be based on percent earned of the total, where 
    90-  %    A
    80-89%    B
    70-79%    C
    60-69%    D
      -59%    F

Students must realize that their grade will largely be based on
demonstrated competence on examinations. Doing will on homework alone will
not assure passing in the class.
    Quizzes and Homework 100 points
    Exam I, II, III      300 points (three hourly exams)
    Final Exam           200 points
    Total Points         600 points




Students must bring picture ID's of themselves to all exams.




Attendance: Attendance is required in this course.
From the 3rd absence, 5 points will be subtracted from the total of 600
points. Any possible doctor's notes are included in the 2 excused ones.




Quizzes: There may be some quizzes in the class (not pre-announced).
There will be no makeup quizzes.




Make-ups: Make-ups on examinations will be permitted
only for very important reasons. When possible, permission for a
make-up should be obtained in advance. In all cases, written verification
of the circumstances requiring the make-up must be submitted to the instructor.
The final decision on whether or not to give a make-up is the sole responsibility
of the instructor. Make-ups on quizzes will not
be given. 




Grading Policy: All questions regarding the instructor's
grading of exams, quizzes, lab projects and/or
homework must be presented to the instructor within 1 week from the date
the papers are brought to class to be returned. Students should check all
adding of credits on their work to see that proper credit has been assigned.




Disabilities: Any student in this course who has
a disability that may prevent him or her from fully demonstrating his or
her abilities should contact me personally as soon as possible so we can
discuss accommodations necessary to ensure full participation and facilitate
your education opportunity.
Cheating. All cases of academic misconduct will
be reported to the Dean for prosecution. Cheating is a serious offense
which can have disastrous consequences for your academic career. Don't
do it.




Incompletes and Withdrawals: The grades of "I"
(incomplete) and "W" (withdrawal passing) are not substitutes for the failing
grade of "F." An "I" may be awarded only when the student, due to circumstances
beyond his/her control, will be unable to complete a small, but significant
portion of the course. In addition, the student must have a reasonable
chance, in the judgment of the instructor, to complete the missing work.
An incomplete will not be awarded if the missing work is so substantial that
the student must "sit in" on the entire course in a later semester.
In this case, if passing, the student should consider withdrawal. After
February 26, a grade of "W" will not be awarded to any student in failing
standing in the course. Up until then any student, whether passing or failing,
may withdraw with an "automatic W." From the beginning of 
April 5, and on, any passing student wishing to withdraw must, in
addition, have permission of their Dean (which is quite impossible).
No Record of Grade on Dropped Courses   January 17-30
Final Day to Add a Class                January 20
Automatic Grade of W for Dropped Course January 31 - March 30
Grade of W or F for Dropped Course(s)   February 27 - May 4
Petition to College Dean to Drop Course April 2-May 6

The Final Exam Day is 
Mon May 8,   8:00 AM - 10:00 AM.
Please plan now to attend. Never arrange for conflicting travel plans.




Advice to Students: For success in the course, a good attitude
and an eagerness for completing assignments promptly are essential. Class
attendance is a must. Students who have outside employment should carefully
weigh the effects of a lack of study time if grades drop. Perhaps other
sacrifices will allow more study time and better success. 
Students should expect to spend at least two hours on homework for each
regular class session. 
Please take this advice seriously. The start of a new semester provides
a great opportunity to you. Be serious about your future. Good Luck!
