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

Predicted Final Average

  EXTREMELY UNCERTAIN ESTIMATE.  I am making the prediction
  early this semester because our final exam is on the first
  day of exams, and only two days after our final test.  To
  make the prediction, I used the first three test scores
  with one drop, the first 11 quiz scores with 3 drops, the
  HW scores through the first 12 HW's (i.e. the midterm HW
  averages), and the PRS scores through lecture 21.  It is
  impossible at this time to make a more reliable estimate.
  As to what the effects might be due to the 4th test, or
  due to the remaining quizzes, HWs, and PRS scores -- your
  estimate is as good as mine.  This estimate is only made
  to give you some idea of your standing in the class at this
  time, and should in no way be taken as a reliable predictor
  of the final grade scale.  GBA

  59 students have taken two or more tests (and are still
     registered). For these 59 students, the overall averages are

                     %     points

      test         63.67    38.20

      HW           79.51     6.36

      QUIZ         67.27     4.71

      PRS          80.46     4.02

   overall                  53.3  out of 80 possible pre-exam points

                       or   66.6%  <-- Predicted Pre-Exam Average

    Assuming an average of 65 on the final, or 13 out of
20 points, results in a predicted overall average of 66.3.
With this predicted average a possible breakdown of grades
would be:

                49.3 - 60.2   D
                60.3 - 72.2   C
                72.3 - 83.2   B

The true final grade scale ultimately depends on overall class 
performance on the 4th Test and on the Final Exam (as well as
the remaining quizzes, HWs, and PRS scores).  Also, the final 
grade scale will be selected so as to find gaps in the final 
grade distribution.

4th test 

           51 students took test 4

           11 made below 42

           40 scored 42 or more

       for those 40 the average was 78.6 (62.9%)

       test 4 grades


      Of the 50 students who had taken three or more tests and 
      had more than 140 HW points, 48 took the final exam.
      For those 48 students the final exam average is 

            23.2 out of 40, or 58.0%.

       exam grades


    48 students took 3 or more tests plus the final exam
       and had more than 140 HW points.

       for those 63 here are the averages:

                 %      points
         HW    81.86     6.55    
         quiz  69.21     4.84
         prs   90.23     4.51
         test  64.56    38.74

         exam  58.03    11.61

      overall           66.25 (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:

                    46.2 - 56.8   D
                    56.9 - 69.9   C
                    70.0 - 79.9   B

Letter grades were assigned strictly according to this
scale.  The highest E is 42.9, the lowest D is 46.2;  the
highest D is 54.5, the lowest C is 56.9;  the highest C
is 69.1, the lowest B is 70.5;  the highest B is 75.6,
and the lowest A is 80.0.  The smallest gap between
levels is 1.4 points between C to B.

If you find a significant error, please stop by my office.
The best day to stop by is Friday afternoon (5/07).  After
that any corrections require a Change-of-Grade form.  After
Friday you should call or email before stopping by to make 
sure that I will be there.  I will be off campus from 
5/15/04 - 5/26/04.  For information on how to figure your
