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
109 students took test 1
23 made below 36
86 scored 36 or more
for those 86 the average was 58.6
2nd test
106 students took test 2
21 made below 47
85 scored 47 or more
for those 85 the average was 70.2
3rd test
103 students took test 3
20 made below 43
83 scored 43 or more
for those 83 the average was 63.5
4th test
97 students took test 4
21 made below 34
76 scored 34 or more
for those 76 the average was 52.5
5th test
95 students took test 5
19 made below 40
76 scored 40 or more
for those 76 the average was 60.4
Pre-Exam Average
97 students have taken 4 or more tests.
for those 97 here are the averages:
HW 7.6 (out of 10)
quiz 9.0 (out of 10)
test 60.1 (multiply by 0.6 to get #points)
overall 52.6 (out of 80 pre-exam points)
Assuming an average of 60 on the final, or 12 out of
20 points, results in a predicted overall average of 64.6.
With this predicted average a possible breakdown of grades
would be:
49 - 59.5 D
59.5 - 70.5 C
70.5 - 81 B
You should figure your pre-exam total then figure how many
exam points (out of 20 possible) you need to get the grade
that you want. Remember that the true final grade scale
ultimately depends on overall class exam performance.
Final Average
96 students took 4 or more tests plus the final exam
for those 96 here are the averages:
HW 7.6 (out of 10)
quiz 9.0 (out of 10)
test 60.4 (multiply by 0.6 to get #points)
exam 10.9 (out of 20)
overall 63.7 (out of 100)
The final grade scale was selected so as to find gaps
in the grade distribution. Here is that final scale:
48 - 58.5 D
58.5 - 69.5 C
69.5 - 80 B
Letter grades were assigned strictly according to this
scale. The highest E is 46.6, the lowest D is 49.3; the
highest D is 57.8, the lowest C is 58.7; the highest C
is 69.0, the lowest B is 70.1; the highest B is 78.8,
and the lowest A is 80.0. The smallest gap between
levels is 0.9 points between D and C.
Here is the final grade distribution for the 96 students
who took the final exam.
