Class Mailing List
•
All students should register themselves with the class list,
which is used for all technical discussions concerning the
course. To register, go to the following web page, and
follow the instructions:

•
You will be notified in return that you are a list
participant. Please send all of your questions to this list
(not to the instructor) so that everyone can participate.

• Students that do not already have a CIMS Sun network
account should apply for one as follows:

Grading
• No Examinations!
• Assignments will require that you write programs or program
fragments and answer some questions about the assignment.
• Assignments will be assigned a fractional weight a (percentage) of the
final grade ( haven’t figured it out yet).
• We will grade your programs somewhat subjectively. You must do
more than “get the right answer” to earn full credit. For example, we
will look at your program structure and mechanisms and deduct if you
write terribly inefficient code (poor data structures, excessive memory
use, etc).
Grading Schedule
Grades will be given according to the following schedule:
A
93 - 100

Rules for Working on Assignments
• All assignments must be done individually (see Cheating
below).
• Unless stated otherwise in the assignment, all writing and
coding must be original.
• All assignments must be emailed to the appropriate grader.
To avoid problems with "lost emails" ("the Internet ate my
homework") you should save a copy of your EMAIL (not
simply the assignment itself).
Cheating Policy
You should NOT
1.
2.
3.
Copy any part of another student's homework answers.
Allow another student to copy your homework.
Copy any part of code found in a book, magazine, the Internet, or other
resource. Present the work of another as your own. If you use the idea of
another in your work, you MUST provide appropriate attribution (that is,
cite the work and the author).
–
The penalty for first cheating offense will be a grade of F for the course.
How to hand in Assignments
+
Late Assignments
• Homework problems must be submitted by email to the

– Assignment number (1, 2, …)
• Homework may be submitted up to one week late, but will
receive a 10% penalty.
• NO credit will be given for ANY assignment submitted
