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  

  92 students have taken four or more tests and have more
     than 100 HW points.  For these 92 students, the
     overall averages are

        test         65.0  (multiply by 0.6 to get # of points)

        HW            7.9

        QUIZ          8.0

     overall         54.9 points out of 80 possible pre-exam points

                or   68.6%  <-- Pre-Exam Average

    Assuming an average of 65 on the final, or 13 out of
20 points, results in a predicted overall average of 67.9.
With this predicted average a possible breakdown of grades
would be:

                51.8 - 62.3   D
                62.4 - 73.4   C
                73.5 - 84.0   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.


      Of the 92 students who had taken four or more tests and 
      had more than 100 HW points, 90 took the final exam.
      For those 90 students the final exam average is 

            26.8 out of 40, or 67.0%.


 90 students took 4 or more tests plus the final exam

       for those 90 here are the averages:

         HW     7.85 (out of 10)
         quiz   8.0  (out of 10)
         test  64.6  (multiply by 0.6 to get #points)

         exam  26.8  (out of 40 - divide by 2 to get #points)

      overall  68.0  (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:

                    49.5 - 61.0   D
                    61.1 - 72.2   C
                    72.3 - 83.7   B

Letter grades were assigned strictly according to this
scale.  The highest E is 47.4, the lowest D is 49.5;  the
highest D is 60.5, the lowest C is 61.1;  the highest C
is 70.4, the lowest B is 72.3;  the highest B is 82.9,
and the lowest A is 83.8.  The smallest gap between
levels is 0.6 points between D to C.

    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 evening or Friday between 10:30 and 11:30 AM.  After
that time any change of grade requires a change of grade form.
