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
123 students have taken four or more tests and have more
than 600 HW points. For these 123 students, the
overall averages are
% points
HW 87.5 7.00
QUIZ 75.9 5.31
PRS 89.4 4.47
test 59.3 35.55
_________________________________
overall 52.33 points out of 80 possible
pre-exam points
or 65.4% <-- Pre-Exam Average
Assuming an average of 65 on the final, or 13 out of
20 points, results in a predicted overall average of 65.3.
With this predicted average a possible breakdown of grades
would be:
49.2 - 59.7 D
59.8 - 70.7 C
70.8 - 81.3 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 123 students who had taken four or more tests and
had more than 600 HW points, 122 took the final exam. One
student who had no chance to pass also took the final.
For the 123 students who took the final, the final exam
average is
23.8 out of 40, or 59.5%.

FINAL AVERAGE
(Some mistakes were found in the initial TA reports; there
may still be some more small changes. GBA)
122 students took 4 or more tests plus the final exam and
had more than 600 HW points.
For those 122 here are the averages:
% points
HW 88.05 7.04
QUIZ 76.46 5.35
PRS 89.92 4.50
test 59.95 35.97 (some corrections were made
to the test 5 scores)

_________________________________
overall 64.8 <-- final average
The final grade scale is a compromise between finding
large gaps in the grade distribution and staying reasonably
close to the predicted scale. Here is the final scale:
45.6 - 57.3 D
57.4 - 69.8 C (above 66.9 is C+)
69.9 - 79.0 B (below 74 is B-, above 77 is B+)
above 79.0 A (below 83 is A-, above 90 is A+)
Letter grades were assigned strictly according to this
scale. The highest E is 41.5, the lowest D is 45.6; the
highest D is 56.7, the lowest C is 57.4; the highest C
is 69.2, the lowest B is 69.9; the highest B is 78.4,
and the lowest A is 79.1. The smallest gap between
levels is 0.7 points between D to C, between C to B,
and between A and B.
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
before May 26th. I will be away from campus from May 27th to
June 25th. At this point any change requires 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 122 students
who took four or more tests plus the final exam.
