                Homework and Pop Quizzes                10%
                Computer Project                        10%
                Exam 1                                  20%
                Exam 2                                  20%
                Exam 3                                  20%
                Comprehensive Exam                      20%

GRADING SCALE:

        A       90 - 100%       (highest degree of excellence)
        B       80 - 89%        (superior)
        C       70 - 79%        (average)
        D       60 - 69%        (quality of work that is minimum for receiving course credit)
        F       < 60%           (failure)

Note: The lower limit in each grade range may be lowered slightly such that the division between letter grades occur at any large gaps in the grade spectrum. This adjustment will be determined only after the final averages are computed and may or may not alter the grade scale.

• Approximately one homework assignment will be given per class period.
  
  Homework assignments are due at the beginning of the period on the indicated date. Late homework WILL NOT be accepted.
  
  Discussion of homework problems among students is encouraged. However, any exchange of written information regarding the homework problems is considered cheating. Copying homework solutions from solution manuals or from previous quarters is also considered cheating. Cheating will be dealt with harshly (see page 25 of the 1996-1997 bulletin regarding academic misconduct).
  
  Homework must be neat and legible. For each problem, provide pertinent information to define the problem, list quantities to be found, and provide a solution that is easy to follow. All intermediate steps must be clearly shown; answers should be clearly marked and must include appropriate units.

COMPUTER PROJECT:

• One computer project will be assigned during the quarter.
  
  The computer project must be submitted as a report. The required format for the report will be given when the project is assigned.
  
  All work on the projects MUST be completed individually (no sharing of information is allowed). Cheating will be dealt with harshly (see page 25 of the 1996-1997 bulletin regarding academic misconduct).
  
  Late projects will be penalized ten percent per day, excluding Saturday and Sunday (4 days late means that the maximum possible score is 60%).

• Regular and Punctual class attendance is expected (refer to page 21 of the 1996-1997 bulletin regarding attendance).
  
  An unexcused absence for an examination will result in a zero grade for that test.
