```NOTE:  In reporting the averages from the test we drop
the lowest scores.  This is because 20% (1 out
of 5) 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

1st test

161 students took test 1

24 made below 50

137 scored 50 or more

for those 137 the average was 74.5

2nd test

155 students took test 2

36 made below 40

119 scored 40 or more

for those 119 the average was 58.8

3rd test

159 students took test 3

36 made below 40

123 scored 40 or more

for those 123 the average was 69.9

4th test

139 students took test 4

26 made below 45

113 scored 45 or more

for those 113 the average was 66.8

5th test

132 students took test 5

27 made below 35

105 scored 35 or more

for those 105 the average was 57.0

Pre-Exam average

139 students have taken 4 or more tests
(note:  this number was incorrectly reported
earlier as 132)

for those 139 here are the averages:

HW    7.8   (out of 10, 1 HW remaining)
quiz  7.2   (out of 10)
(we ended up dropping three quizzes
and dividing the total points by 9)
demo  4.3   (out of 5)
test 64.5   (multiply by 0.6 to get #points)

overall 58.0

Assuming 1 more HW point for the remaining turn-in
and 9.7 points out of 15 on the final results in a
predicted average of 68.7.  With this predicted average
a possible breakdown of grades would be:

52 - 63   D
63 - 75   C
75 - 86   B

You should figure your pre-exam total then figure how many
exam points (out of 15 possible) you need to get the grade
that you want.

Final Average

133 students took 4 or more tests plus the final exam

for those 133 here are the averages:

HW    8.4   (out of 10)
quiz  7.3   (out of 10)
demo  4.4   (out of 5)
test 65.3   (multiply by 0.6 to get #points)

exam  9.2   (out of 15)

overall 68.5   (out of 100)

The final grade scale was selected so as to find gaps
in the grade distribution.  Here is that final scale:

50.3 - 61.6   D
61.6 - 74.4   C
74.4 - 84.8   B

Letter grades were assigned strictly according to this
scale.  The highest E is 49.5, the lowest D is 50.4;  the
highest D is 61.2, the lowest C is 61.7;  the highest C
is 73.8, the lowest B is 74.5;  the highest B is 82.4,
and the lowest A is 84.9.  The smallest gap between
levels is 0.5 points between D and C.

Here is the final grade distribution for the 133 students
who took the final exam.
