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

Pre-exam average 

       149 students have taken 4 or more tests

       for those 149 here are the averages:

         HW    7.1   (out of 10 possible, 2 HW turn-ins remaining)
                     (last week's and the final turn-in, at the exam)
         quiz  8.1   (out of 10 possible, best 10 of 13 quizzes)
                      
         test 68.2   (out of 100 possible, best 4 of 5 tests)
                     (multiply by 0.6 to get number of points)

      overall 56.1   (out of 80 possible pre-exam points)


Preliminary pre-exam average is thus  70.1%

     Figuring 0.5 an extra HW point for the remaining turn-ins,
and estimating an average score of 14.0 (70%) on the final
exam results in a predicted final average of 70.6 points.  With
this final average, a possible final grade scale would be

                  54.6 - 65.1   D
                  65.1 - 76.1   C
                  76.1 - 86.6   B

The true final grade scale depends on overall class exam
performance.


Final Average

   145 students took 4 or more tests plus the final exam

       for those 145 here are the averages:

         HW    7.7   (out of 10)
         quiz  7.9   (out of 10)
         test 67.3   (multiply by 0.6 to get #points)

         exam 26.1   (out of 40 - divide by 2 to get #points)

      overall 69.0   (out of 100)


    The final grade scale was selected so as to find gaps
in the grade distribution.  Here is that final scale:

                    51.7 - 62.7   D
                    62.8 - 73.5   C
                    73.6 - 83.9   B

Letter grades were assigned strictly according to this 
scale.  The highest E is 50.7, the lowest D is 51.8;  the 
highest D is 61.9, the lowest C is 62.8;  the highest C 
is 73.1, the lowest B is 73.6;  the highest B is 83.4, 
and the lowest A is 84.0.  The smallest gap between 
levels is 0.5 points between  C and B.

    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
Friday (call beforehand to make sure that I am here) or Monday
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
             HOW TO FIGURE YOUR FINAL GRADE.
