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
50 students took three or more tests (including
the fourth test) and had at least 112 homework
points
for these 50 students
the final CPS average is 4.05 points (out of 5)
the final HW average is 6.43 points (out of 8)
the final quiz average is 5.48 points (out of 7)
the final test average is 46.33 points (57.91% of 80)
the overall average is 62.3 points
Note that the overall average includes all students who took
three or more tests (including the fourth test) and who had
at least 112 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 50 students. With this final average, the final grade
scale is
41.5 - 51.7 D
51.8 - 65.2 C (above 62.9 is C+)
65.3 - 78.0 B (below 67.0 is B-, above 75.5 is B+)
78.1 and up A (below 79.7 is A-, above 93.7 is A+)
with below 41.5 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 39.5, the lowest D is 41.5, the highest D
is 50.7, the lowest C is 51.8, the highest C is 63.0, the
lowest B is 65.3, the highest B is 76.9, and the lowest A
is 78.1. The smallest gap is 1.1 points between D and C.
Grades were assigned strictly based on this scale.

final grade, please contact me before 5 PM MON Aug 11.
