```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

4th test

78 students took test 4

Multiple Choice

58 students earned 30 or more points

for those 58 the average was 43.6 (72.7%)

Problems

53 students earned 25 or more points

for those 53 the average was 43.5 (67.0%)

Overall averages

78 students took all four tests

for these 78 students

the final HW average is 21.0  points (84.0% of 25)

the final test average is 53.8  points (71.7% of 75)

and the overall average is 74.8  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 78 students.  Since the overall average is below 75 there
is a (slight) curve.  The final grade scale is

59.0  -  68.7     D
68.8  -  79.0     C
79.1  -  89.0     B

with below 59.0 as E and above 89.0 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 58.0, the lowest D is 60.2, the
the highest D is 67.5, the lowest C is 68.8, the highest C is
78.5, the lowest B is 80.4, the highest B is 87.6, and the lowest
A is 89.6.  The smallest gap is 1.3 points.  Grades were assigned
strictly based on this scale.
