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

Overall Pre-Exam Average
92 students have taken four or more tests and have more
than 100 HW points. For these 92 students, the
overall averages are
test 65.0 (multiply by 0.6 to get # of points)
HW 7.9
QUIZ 8.0
________________________
overall 54.9 points out of 80 possible pre-exam points
or 68.6% <-- Pre-Exam Average
Assuming an average of 65 on the final, or 13 out of
20 points, results in a predicted overall average of 67.9.
With this predicted average a possible breakdown of grades
would be:
51.8 - 62.3 D
62.4 - 73.4 C
73.5 - 84.0 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 EXAM
Of the 92 students who had taken four or more tests and
had more than 100 HW points, 90 took the final exam.
For those 90 students the final exam average is
26.8 out of 40, or 67.0%.
FINAL AVERAGE
90 students took 4 or more tests plus the final exam
for those 90 here are the averages:
HW 7.85 (out of 10)
quiz 8.0 (out of 10)
test 64.6 (multiply by 0.6 to get #points)
exam 26.8 (out of 40 - divide by 2 to get #points)
overall 68.0 (out of 100) <-- Final Average
The final grade scale was selected so as to find gaps
in the grade distribution. Here is that final scale:
49.5 - 61.0 D
61.1 - 72.2 C
72.3 - 83.7 B
Letter grades were assigned strictly according to this
scale. The highest E is 47.4, the lowest D is 49.5; the
highest D is 60.5, the lowest C is 61.1; the highest C
is 70.4, the lowest B is 72.3; the highest B is 82.9,
and the lowest A is 83.8. The smallest gap between
levels is 0.6 points between D to C.
Be sure to check your TA's computation of your final grade.
If you find a significant error the best time to see me is
Thursday evening or Friday between 10:30 and 11:30 AM. After
that time any change of grade requires a change of grade form.
