NOTE:  In reporting the averages from the test we drop
       the lowest scores.  This is because 25% (2 out
       of 8) of all scores will eventually be dropped.
       In comparing your average with the class average
       you need to compare with an average which is
       representative of the final average.  Dropping
       the lowest scores before reporting the average
       is one way of estimating the effect of the
       final drops. GBA

Overall averages

       100 students took all four tests 
           and had more than 90 HW points

           for these 100 students

             the final HW average is  8.4  points 

           the final Quiz average is  8.3  points 

           the final test average is 59.7% (multiply by .8 to
                                            get number of points)

          and the overall average is 64.5  points


Note that the overall average includes all students who took
four tests.  The test average is computed by dropping the
lowest MC and the lowest Problems section for each student, 
computing each student's average, and then computing a global 
average for all 100 students.  Also, adjustments were made to 
the HW and Quiz averages to account for different grading 
practices for the five TAs.  With this final average, the 
final grade scale is

                     46.8  -  57.3     D
                     57.4  -  68.0     C
                     68.1  -  78.4     B

with below 46.8 as E and above 78.4 as A.  The final scale was
selected so as to find gaps in the distribution.  With the scale
as given above the highest E is 44.4, the lowest D is 46.8, the
the highest D is 56.5, the lowest C is 57.4, the highest C is
66.7, the lowest B is 68.1, the highest B is 78.0, and the lowest
A is 78.5.  The smallest gap is 0.5 points between A and B.  
Grades were assigned strictly based on this scale.

     Be sure to check your TA's computation of your final grade.
