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

overall 53.66 points out of 80 possible
pre-exam points
or 67.1% ... Pre-Exam Average
Assuming an average of 60 on the final, or 12 out of
20 points, results in a predicted overall average of 65.7.
Since we now provide histograms throughout the semester
which you may use to determine your approximate standing
in the class, we no longer use the above data to attempt
to predict the final grade scale.
FINAL EXAM
For the 138 students who took the final and had
nonzero TP scores, and had also earned 665 or
more HW points, the final exam average is
27.30 out of 40, or 68.3%.

FINAL AVERAGE
138 students took 3 or more MC parts, and 3 or more
free response parts, plus the final exam, and
had a nonzero TP score and more than 665 HW

_________________________________
overall 68.88 <-- final average
The final grade scale was primarily determined by the
large gaps in the grade distribution. Here is that final
grade scale.
41.7 - 55.0 D
55.1 - 68.8 C (above 67.8 is C+)
68.9 - 79.2 B (below 72.2 is B-, above 78.6 is B+)
above 79.3 A (below 81.3 is A-, above 94.0 is A+)
Letter grades were assigned strictly according to this
scale. The highest E is 39.3, the lowest D is 41.8; the
highest D is 54.1, the lowest C is 55.1; the highest C
is 68.2, the lowest B is 68.9; the highest B is 78.8,
and the lowest A is 79.3. The smallest gap between
levels is 0.5 points between B to A.
If you find a significant error in your recorded grades,
the best time to see me is before NOON FRI May 14th.
Sourabh's students should contact Sourabh first, then me.
Lu's students should contact me directly, as Lu has already
left for China during break. After FRI noon 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 138 students
who took three or more MC and free-response test parts plus
the final exam, and had nonzero TP scores, and received
more that 665 HW points.
