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.  These posted averages are not
       used in any way in calculating the final class
       average. GBA

Overall averages

        46 students took three or more tests (including
           the fourth test) and had at least 520 WebAssign
           HW points

           for these 46 students

             the final TP average is  4.12 points (82.4% of 5 points)

             the final HW average is  6.63 points (82.9% of 8 points)

           the final quiz average is  5.24 points (74.9% of 7 points)

           the final test average is 45.41 points (56.76% of 80 points)

              the overall average is 61.4  points  


Note that the overall average includes all students who took
three or more tests (including the fourth test) and who had
at least 520 HW points.  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 46 students.  With this final average, the final grade
scale is

           41.2  -  49.4     D   
           49.5  -  62.2     C   (above 59.8 is C+)
           62.3  -  78.0     B   (below 65.2 is B-, above 74.5 is B+)
           78.1 and up       A   (below 81.4 is A-, above 92.3 is A+)

with below 41.2 as E.  The final scale was selected so as to
find gaps in the distribution.  With the scale as given above 
the highest E is 38.1, the lowest D is 41.3, the highest D is
47.5, the lowest C is 49.6, the highest C is 60.2, the lowest B
is 62.4, the highest B is 74.5, and the lowest A is 78.2.  The
smallest gap is 2.1 points between D and C.  Grades were assigned
strictly based on this scale.
