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. GBA

Overall Pre-Exam Average 

Note: Some errors were found in the reported averages for
      five sections.  These corrections were put in on
      Mon 5/07 at 11 PM.

 142 students have taken four or more tests and have more
     than 100 HW points.  For these 142 students, the
     overall averages are

        test         64.1  (multiply by 0.6 to get # of points)

        HW            8.4

        QUIZ          9.1

     overall         56.0 points out of 80 possible pre-exam points

                or   70.0%  <-- Pre-Exam Average

     Estimating an average score of 14.0 (70%) on the final
exam results in a predicted final average of 70.0 points.  With
this final average, a possible final grade scale would be

                  54.0 - 64.5   D
                  64.5 - 75.5   C
                  75.5 - 86.0   B

The true final grade scale depends on overall class exam


      Of the 142 students who had taken four or more tests and 
      had more than 100 HW points, 132 took the final exam.
      For those 132 students the final exam average is 

            25.9 out of 39, or 66.4%.

      (We had to throw out one question)

       final exam grades


132 students took 4 or more tests plus the final exam

       for those 132 here are the averages:

         HW     8.5  (out of 10)
         quiz   9.3  (out of 10)
         test  65.2  (multiply by 0.6 to get #points)

         exam  25.9  (out of 39 - multiply by (20/39) to get #points)

      overall  70.2  (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:

                    54.0 - 64.5   D
                    64.6 - 75.5   C
                    75.6 - 86.1   B

Letter grades were assigned strictly according to this
scale.  The highest E is 53.3, the lowest D is 54.1;  the
highest D is 63.9, the lowest C is 64.7;  the highest C
is 75.2, the lowest B is 76.5;  the highest B is 85.6,
and the lowest A is 86.3.  The smallest gap between
levels is 0.7 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
Thursday afternoon or Friday between 10:30 and 11:30 AM.  After
that time any change of grade requires a change of grade form.
