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
Be sure to check your TA's computation of your final grade.
If you find a significant error the best time to see me is
between 10 and 11 AM Monday July 7. After that time any
change of grade requires a change of grade form. For
