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. These posted test averages are not used
in any way in computing the final overall class
average. GBA

Overall Pre-Exam Average
102 students have taken four or more tests and have more
than 600 HW points. For these 102 students, the
overall averages are
% points

HW 72.81 5.82 <== this number is incorrect
QUIZ 72.64 5.08
PRS 77.06 3.85
__________________________________
overall 50.9 out of 80 possible pre-exam points
or 63.6% <-- Predicted Pre-Exam Average
Assuming an average of 65 on the final, or 13 out of
20 points, results in a predicted overall average of 63.9.
With this predicted average a POSSIBLE breakdown of grades
would be:
48.7 - 58.6 D
58.7 - 69.1 C
69.2 - 79.1 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. Also,
the final grade scale will be selected so as to find gaps
in the final grade distribution.
For information on how to figure your grade so as to
compare with this predicted average please see
HOW TO FIGURE YOUR FINAL GRADE.
FINAL EXAM
103 students took the final exam. For those 103
students the final exam average is
24.14 out of 40, or 60.35%.

FINAL AVERAGE
97 students took 4 or more tests plus the final exam
and had more than 120 HW points (there were 6 students
who took the final exam who either did not take 4 or
more tests or else who had less than 600 HW points).
for those 97 here are the averages:
% points
test 61.67 37.00
HW 84.94 6.80 <== the pre-exam HW average
was figured incorrectly
QUIZ 77.86 5.45
PRS 79.40 3.97
EXAM 61.65 12.33
__________________________________
overall 65.6 (out of 100) <-- Final Average
The final average is higher than the predicted final
average primarily because of the mistake that was made,
before the exam, in calculating the HW average; but also,
because there were 5 students who had taken four or more
tests and had more than 600 HW points who chose not to
take the final exam. Nevertheless, we felt it would be
unfair to significantly raise the predicted grade scale.
The final grade scale was selected so as to find gaps
in the grade distribution. Here is that final scale:
48.4 - 58.9 D
59.0 - 69.3 C (above 67.3 is C+)
69.4 - 78.3 B (below 72 is B-, above 76 is B+)
78.4 and up A (below 83 is A-, above 93 is A+)
Letter grades were assigned strictly according to this
scale. The highest E is 46.5, the lowest D is 48.4; the
highest D is 57.9, the lowest C is 59.0; the highest C
is 67.9, the lowest B is 70.4; the highest B is 77.7,
and the lowest A is 78.4. The smallest gap between
levels is 0.7 points between B to A.
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
Friday Dec 17 between 2:00 - 4:00 PM. After that time any
change will require that we fill out a change-of-grade form.
For information on how to figure your final grade see
HOW TO FIGURE YOUR FINAL GRADE.
Here is the final grade distribution for the 97 students
who took four or more tests plus the final exam, and had
at least 600 HW points.
