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

1st test 

   161 students took test 1 

    24 made below 50 

   137 scored 50 or more

       for those 137 the average was 74.5 
  

2nd test

   155 students took test 2

    36 made below 40

   119 scored 40 or more

       for those 119 the average was 58.8



3rd test

   159 students took test 3

    36 made below 40

   123 scored 40 or more

       for those 123 the average was 69.9



4th test

   139 students took test 4

    26 made below 45

   113 scored 45 or more

       for those 113 the average was 66.8


5th test

   132 students took test 5

    27 made below 35

   105 scored 35 or more

       for those 105 the average was 57.0


Pre-Exam average

   139 students have taken 4 or more tests
     (note:  this number was incorrectly reported
             earlier as 132)

       for those 139 here are the averages:

         HW    7.8   (out of 10, 1 HW remaining)
         quiz  7.2   (out of 10)
                     (we ended up dropping three quizzes
                      and dividing the total points by 9)
         demo  4.3   (out of 5)
         test 64.5   (multiply by 0.6 to get #points)

      overall 58.0 

Assuming 1 more HW point for the remaining turn-in
and 9.7 points out of 15 on the final results in a 
predicted average of 68.7.  With this predicted average
a possible breakdown of grades would be:

                    52 - 63   D
                    63 - 75   C
                    75 - 86   B

You should figure your pre-exam total then figure how many
exam points (out of 15 possible) you need to get the grade
that you want.



Final Average

   133 students took 4 or more tests plus the final exam

       for those 133 here are the averages:

         HW    8.4   (out of 10)
         quiz  7.3   (out of 10)
         demo  4.4   (out of 5)
         test 65.3   (multiply by 0.6 to get #points)

         exam  9.2   (out of 15)

      overall 68.5   (out of 100)


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

                    50.3 - 61.6   D
                    61.6 - 74.4   C
                    74.4 - 84.8   B

Letter grades were assigned strictly according to this 
scale.  The highest E is 49.5, the lowest D is 50.4;  the 
highest D is 61.2, the lowest C is 61.7;  the highest C 
is 73.8, the lowest B is 74.5;  the highest B is 82.4, 
and the lowest A is 84.9.  The smallest gap between 
levels is 0.5 points between D and C.

Here is the final grade distribution for the 133 students
who took the final exam.
