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

        87 students took all four tests and 
           had at least 90 homework points

           for these 87 students

             the final HW average is  8.2  points 

           the final quiz average is  7.7  points 

           the final test average is 57.6% (46.1 points)

          and the overall average is 62.0  points


Note that the overall average includes all students who took
four tests.  The test average is computed by dropping the
lowest MC section and the lowest problem section for each 
student (except one section of test 4 must be kept), computing 
each student's average, and then computing a global average 
for all 87 students.  With this final average, the final grade
scale is

                     42.8  -  53.0     D
                     53.1  -  65.6     C
                     65.7  -  75.6     B

with below 42.8 as E and above 75.6 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 38.3, the lowest D is 42.8, the
the highest D is 52.3, the lowest C is 53.1, the highest C is
64.7, the lowest B is 65.7, the highest B is 73.8, and the lowest
A is 75.7.  The smallest gap is 0.8 points between D and C.
Grades were assigned strictly based on this scale.
