NOTE: In reporting the averages from the test we drop
the lowest scores. This is because 25% (1 out
of 4) 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 averages are not used in
any way in computing the final overall class
average. GBA

Predicted Final Average
DISCLAIMER: THIS PREDICTED FINAL GRADE SCALE IS AN
EXTREMELY UNCERTAIN ESTIMATE. I am making the prediction
early this semester because our final exam is on the first
day of exams, and only two days after our final test. To
make the prediction, I used the first three test scores
with one drop, the first 11 quiz scores with 3 drops, the
HW scores through the first 12 HW's (i.e. the midterm HW
averages), and the PRS scores through lecture 21. It is
impossible at this time to make a more reliable estimate.
As to what the effects might be due to the 4th test, or
due to the remaining quizzes, HWs, and PRS scores -- your
estimate is as good as mine. This estimate is only made
to give you some idea of your standing in the class at this
time, and should in no way be taken as a reliable predictor
of the final grade scale. GBA
59 students have taken two or more tests (and are still
registered). For these 59 students, the overall averages are

test 63.67 38.20
HW 79.51 6.36
QUIZ 67.27 4.71
PRS 80.46 4.02
__________________________________
overall 53.3 out of 80 possible pre-exam points
or 66.6% <-- 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 66.3.
With this predicted average a possible breakdown of grades
would be:
49.3 - 60.2 D
60.3 - 72.2 C
72.3 - 83.2 B
The true final grade scale ultimately depends on overall class
performance on the 4th Test and on the Final Exam (as well as
the remaining quizzes, HWs, and PRS scores). Also, the final
grade scale will be selected so as to find gaps in the final
grade distribution.

with this predicted average please see

4th test
51 students took test 4

FINAL EXAM
Of the 50 students who had taken three or more tests and
had more than 140 HW points, 48 took the final exam.
For those 48 students the final exam average is
23.2 out of 40, or 58.0%.

FINAL AVERAGE
48 students took 3 or more tests plus the final exam
and had more than 140 HW points.
for those 63 here are the averages:
% points
HW 81.86 6.55
quiz 69.21 4.84
prs 90.23 4.51
test 64.56 38.74
exam 58.03 11.61
overall 66.25 (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:
46.2 - 56.8 D
56.9 - 69.9 C
70.0 - 79.9 B
Letter grades were assigned strictly according to this
scale. The highest E is 42.9, the lowest D is 46.2; the
highest D is 54.5, the lowest C is 56.9; the highest C
is 69.1, the lowest B is 70.5; the highest B is 75.6,
and the lowest A is 80.0. The smallest gap between
levels is 1.4 points between C to B.
Be sure to check my computation of your final grade.
If you find a significant error, please stop by my office.
The best day to stop by is Friday afternoon (5/07). After
that any corrections require a Change-of-Grade form. After
Friday you should call or email before stopping by to make
sure that I will be there. I will be off campus from
5/15/04 - 5/26/04. For information on how to figure your
final grade see
HOW TO FIGURE YOUR FINAL GRADE.
Here is the final grade distribution for the 48 students
who took three or more tests plus the final exam, and had
