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
46 students took three or more tests (including
the fourth test) and had at least 750 MP HW points
for these 46 students
the final TP average is 4.19 points (83.8% of 5 points)
the final HW average is 6.32 points (79.0% of 8 points)
the final quiz average is 4.95 points (70.7% of 7 points)
the final test average is 40.36 points (50.45% of 80 points)
the overall average is 55.8 points
Note that the overall average includes all students who took
three or more tests (including the fourth test) and who had
at least 750 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 46 students. With this final average, the final grade
scale is
35.1 - 46.7 D
46.8 - 56.3 C (above 53.1 is C+)
56.4 - 72.5 B (below 57.8 is B-, above 68.8 is B+)
72.6 and up A (below 75.0 is A-, above 86.2 is A+)
with below 35.1 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 33.8, the lowest D is 35.1, the highest D is
44.3, the lowest C is 46.8, the highest C is 53.9, the lowest B
is 56.4, the highest B is 68.9, and the lowest A is 72.7. The
smallest gap is 1.3 points between E and D. Grades were assigned
strictly based on this scale.
