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
78 students have taken four or more tests and have more
than 650 HW points. For these 78 students, the
overall averages are (updated with reported numbers
from all sections on TUE 5/8 at 10 AM)
% points
HW 75.9 6.07
QUIZ 64.2 4.49
PRS 72.0 3.60

overall 44.88 points out of 80 possible
pre-exam points
or 55.8% <-- Pre-Exam Average
Assuming an average of 65 on the final, or 13 out of
20 points, results in a predicted overall average of 57.9.
With this predicted average a possible breakdown of grades
would be:
42.4 - 52.3 D
52.4 - 63.3 C
63.4 - 73.3 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
While 78 students had taken four or more tests and had
more than 650 HW points, 82 students took the final exam.
For the 78 students who took the final and had a chance
to pass, the final exam average is
17.4 out of 40, or 43.5%.

FINAL AVERAGE
(Some mistakes were found in the initial TA reports; also,
adjustments were made to TA quiz averages to account for
differing TA quiz grading practices.)
78 students took 4 or more tests plus the final exam and
had more than 650 HW points.
For those 78 here are the averages:
% points
HW 77.20 6.18
QUIZ 77.94 5.46
PRS 72.20 3.61

overall 54.6 <-- final average
The final grade scale was primarily determined by the
large gaps in the grade distribution. Here is the final
scale:
38.8 - 49.9 D
50.0 - 62.0 C (above 59.6 is C+)
62.1 - 69.5 B (below 65 is B-, above 68.4 is B+)
above 69.5 A (below 72 is A-, above 82 is A+)
Letter grades were assigned strictly according to this
scale. The highest E is 36.8, the lowest D is 38.8; the
highest D is 48.3, the lowest C is 50.1; the highest C
is 59.7, the lowest B is 62.6; the highest B is 68.6,
and the lowest A is 69.6. The smallest gap between
levels is 1.0 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
before Noon May 11th. After that time any change will 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 78 students
who took four or more tests plus the final exam.
