```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

100 students took all four tests
and had more than 90 HW points

for these 100 students

the final HW average is  8.4  points

the final Quiz average is  8.3  points

the final test average is 59.7% (multiply by .8 to
get number of points)

and the overall average is 64.5  points

Note that the overall average includes all students who took
four tests.  The test average is computed by dropping the
lowest MC and the lowest Problems section for each student,
computing each student's average, and then computing a global
the HW and Quiz averages to account for different grading
practices for the five TAs.  With this final average, the

46.8  -  57.3     D
57.4  -  68.0     C
68.1  -  78.4     B

with below 46.8 as E and above 78.4 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 44.4, the lowest D is 46.8, the
the highest D is 56.5, the lowest C is 57.4, the highest C is
66.7, the lowest B is 68.1, the highest B is 78.0, and the lowest
A is 78.5.  The smallest gap is 0.5 points between A and B.
Grades were assigned strictly based on this scale. ```You can also view the grades as a text file:
