```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

1st test

151 students took test 1

121 scored 43 or more

for those 121 the average was 65.2

2nd test

144 students took test 2

114 scored 35 or more

for those 114 the average was 61.7

3rd test

133 students took test 3

105 scored 40 or more

for those 105 the average was 63.4

4th test

124 students took test 4

99 scored 36 or more

for those 99 the average was 59.4

5th test

121 students took test 5

96 scored 37 or more

for those 96 the average was 56.6

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)
exam         59.63   11.93
_________________________________

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.

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
