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  

  86 students have taken four or more tests and have more
     than 100 HW points.  For these 86 students, the
     overall averages are

        test         55.4  (multiply by 0.6 to get # of points)

        HW            7.3

        QUIZ          6.6

     overall         47.1 points out of 80 possible pre-exam points

                or   58.9%  <-- Pre-Exam Average

    Assuming an average of 65 on the final, or 13 out of
20 points, results in a predicted overall average of 60.1.
With this predicted average a possible breakdown of grades
would be:

                44.7 - 54.6   D
                54.7 - 65.6   C
                65.7 - 75.6   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 86 students who had taken four or more tests and 
      had more than 100 HW points, 86 took the final exam.
      For those 86 students the final exam average is 

            24.3 out of 40, or 60.7%.


 86 students took 4 or more tests plus the final exam

       for those 86 here are the averages:

         HW     7.3  (out of 10)
         quiz   6.6  (out of 10)
         test  55.4  (multiply by 0.6 to get #points)

         exam  24.3  (out of 40 - divide by 2 to get #points)

      overall  59.3  (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:

                    42.8 - 52.7   D
                    52.8 - 65.7   C
                    65.8 - 75.7   B

Letter grades were assigned strictly according to this
scale.  The highest E is 41.7, the lowest D is 43.1;  the
highest D is 51.7, the lowest C is 52.8;  the highest C
is 65.1, the lowest B is 66.7;  the highest B is 74.9,
and the lowest A is 76.2.  The smallest gap between
levels is 1.1 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
Tuesday afternoon or Thursday morning between 10:30 and 11:30 AM.  
After that time any change of grade requires a change of grade 
form.  For information on how to figure your final grade see


Here is the final grade distribution for the 86 students
who took four or more tests plus the final exam.
