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

        98 students took all four tests

           for these 98 students

             the final HW average is  9.3  points 

           the final Quiz average is  8.8  points 

           the final test average is 51.3  points (64.1% of 80)

          and the overall average is 69.4  points


Note that the overall average includes all students who took
four tests.  The test average is computed by dropping the
two lowest test 'halves' for each student, computing each
student's average, and then computing a global average for
all 98 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

                     50.6  -  61.0     D
                     61.1  -  73.2     C
                     73.3  -  83.2     B

with below 50.6 as E and above 83.2 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 49.6, the lowest D is 50.6, the
the highest D is 60.0, the lowest C is 61.1, the highest C is
72.2, the lowest B is 73.3, the highest B is 81.3, and the lowest
A is 83.3.  The smallest gap is 1.0 points between D and E.  
Grades were assigned strictly based on this scale.

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