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

for those 36 the average was 35.4 (54.5%)

Overall averages

47 students took three or more tests (including
the fourth test) and had at least 90 homework
points

for these 47 students

the final PRS average is  4.12 points (out of 5)

the final HW average is  5.87 points (out of 8)

the final quiz average is  4.82 points (out of 7)

the final test average is 42.72 points (53.4% of 80)

and the overall average is 57.5  points

Note that the overall average includes all students who took
three or more tests (including the fourth test) and who had
at least 90 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 47 students.  With this final average, the final grade
scale is

40.7  -  50.6     D
50.7  -  61.8     C   (no C+'s this year)
61.9  -  74.3     B   (below 66.0 is B-, no B+'s this year)
74.4 and up       A   (below 76.4 is A-, no A+'s this year)

with below 40.7 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 38.9, the lowest D is 40.7, the the highest
D is 49.4, the lowest C is 50.7, the highest C is 58.3, the
lowest B is 61.9, the highest B is 69.9, and the lowest A is
74.4.  The smallest gap is 1.3 points between D and C.  Grades
were assigned strictly based on this scale.
