Announcements and E-mail
|
Most class related announcements will be either posted on the class
web page or done through e-mail via the discussion board setup for
the class on the
blackboard.
Please do not ask the following types of questions in your e-mail
(although they are appropriate for office hours):
- Here is my understanding of X. Am I right (or is this correct)?
(You can do this for just about everything and in many different ways.
And the instructor and the TA do not have the bandwidth to be able to reply
to too many such questions.)
- I don't understand X. Could you explain X to me?
(It is difficult to give detailed explanations of concepts
over email. And, it is
your responsiblity to come to lectures and ask questions
during lectures if there is something you do not understand.)
|
|
Homework
|
There will on the order of 5 or 6 homework assignments consisting of problems
as well as programming assignments (to be written in C or C++).
|
|
Exams
|
A midterm and a final examination will be given.
The date of the midterm examination will be posted near the
top of the class home page.
The date of the final examination is firm and it is also listed near the
top of the class home page.
Any schedule conflicts regarding the midterm exam date must
be resolved with the instructor at least one week
before the exam date.

Grading
|
-
Homeworks:
|
| 30%
|
Midterm Exam:
|
| 25%
|
Final Exam:
|
| 45%
|
(Please note that the weights are modified by 5%, as announced
at the beginning of the course and discussed in class). The instructor
reserves the right to fail, regardless of overall numeric score,
students who do not show a good faith attempt to complete all
assignments.
Please also note the following:
- The above percentages will be used to calculate your total score.
Final grades (A,B,C,D,or F) will be determined using a modified
curve (i.e., we won't necessarily assign an equal number of failing
grades as passing grades) based on this total score. No other methods
will be considered. (So, please do not ask the instructor to take how
much you have improved since the beginning of the semester into account.
You are expected to try your best from the beginning!)
- We will assign grades of C and below to individuals who do not
perform satisfactorily in the above areas. (i.e., you should not
assume a B- or even C if you perform unsatisfactorily.)
However, we hope that everyone will perform well.
- Your assignments are your own work! No group assignments are allowed.
You are free to talk to other students about
assignments but not to share materials.
We will act harshly at any sign of copying.
- We will not assign incompletes unless it is
for a documented medical reason (in accordance with USC policy).
|
|
Late Policy
|
Unless specified otherwise on a particular assignment, the late policy
is as follows: 50% off for being 1-24 hours late; 75% off for being
25-48 hours late; 100% off for being more than 48 hours late. If you
are unable to complete an assignment due to illness or family emergency,
please contact the instructor as soon as possible to make special
arrangements. A doctor's note is required
as proof of illness or emergency.
Written homeworks are to be turned in at the end (when the
TA leaves) of specified discussion sections.
|
|
Regrading Policy
|
All requests to change grading of homeworks or
exams must be submitted in writing within one week
of the time the initial grade was given. Requests must be specific
and explain why you feel your answer deserves additional credit.
A request to re-grade an assignment can result in the entire assignment
being re-evaluated and as a result the score of any part of
the assignment can be increased or lowered as appropriate.
|
|
Extra Credits
|
No extra credit assignments will be given for this class. So, there
is not need to ask. Try your best from the beginning!
|
|
Class Newsgroup
|
A discussion group is setup for the class on the
blackboard.
The purpose of this forum is for the students to
discuss things with each other as well as ask
the TA and instructor questions.
Students may
not exchange answers here because it would violate academic
integrity policy of USC.
Please make sure that you have read the
Academic Integrity Policy of this course.
|
|
Implicit Student Agreement
|
All work including assignments and exams
must be that of the individual student. It is often
productive to study with other students. However, if any portions of homework
assignments are found to be shared between two (or more)
students, zero credit will be given to all students concerned and all students
will be disciplined. This policy is in the interest of those students who
do their own work, which hopefully applies to all of you in this class.
This policy also holds for assignments involving programming. In
this class, we will use sophisticated automated program checkers to detect
cheating. Be aware that the program checkers have demonstrated very good
results and are widely used within the academic community. Any student
caught cheating will be given zero credit and will be disciplined.
It is the student's responsibility to submit their assignments
to the TA on time.
|
|
Student Responsibilities
|
During the semester you are responsible for completing the assigned
readings, assignments, and exams.
You are expected to read the relevant parts of the required text in detail.
Not all details will be covered in class.
We expect you to attend every class meeting.
If you do happen to miss a session, you are responsible for finding out
what material was covered and if any administrative announcements were
made. You must do so BEFORE the next session (e.g., if there is an assignment
given during the missed session, you are still responsible for completing
it by the next week along with the other students).
|
|
Fairness
|
The instructor must treat all students equally and cannot
give special treatment to any particular student.
Therefore, please do not ask special favors from the
instructor because of your circumstances.
This may seem unfair to you because you believe that you
have special circumstances. But the rule the
instructor follows is that whatever is offered to you,
must be offered to the entire class.
