Grading Basis


Exam Dates


Exam 1: Thursday, February 22

Exam 2: Thursday, April 19

Final:      Tuesday, May 1


Grade Makeup:

• Examinations

Hourly (2)                                             25%

Final                                                       25%

• Group Computer Projects (2)                         30%

• Homework                                                         20%


Students taking NE505 will have extra assignments (computer projects, term paper, homework, etc.) assigned to justify receiving graduate credit.



• Due prior to class when assignment due.

• EOL students should send homework as an attachment to the TA

• No late submittals accepted without prior approval.

• To be eventually worked alone but can be discussed prior to this time.



• Exams will be given during the regularly scheduled class time

• Calculators are allowed for in-class and final exams

Dead Week:

Class assignments, such as homework, term paper or computer project reports, may be due during the last week of classes.


Late Assignments:


Unless stated otherwise, assignments are due at the beginning of class on the designated due date.  Assignments turned in within 24 hours of this time are considered LATE and will be assessed a 25% penalty.   Assignments turned in after 24 hours will be marked and returned to the student, but no credit will be assigned.  To allow for unforeseen circumstances, students are granted a one time exemption if an assignment is turned in by 5:00 PM on the designated due date.  Exceptions to this policy may be granted for documented medical or family emergencies.


Electronic Devices:


Cell phones and other electronic devices (including lap tops) are to be TURNED OFF during class and stored out of view.  No exceptions. Electronic note pads may be used with consent of instructor.


Attendance Policy:


Class attendance is purely optional.  However, students attending class room lectures are required to be on time.  No admittance to the class room will be allowed for students appearing after class has begun.
