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

73 students took all four tests

for these 73 students

the final HW average is  22.5 points (90.1% of 25)

the final test average is  54.8 points (73.1% of 75)

and the overall average is  77.4 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 73 students.  Since the overall average is above 75
there is no curve.  The final letter grades are assigned
strictly based on the following scale:

60.0 - 69.9      D
70.0 - 79.9      C
80.0 - 89.9      B
