NOTE:  In reporting the averages from the test we drop
       the lowest scores.  This is because 25% (2 out
       of 8) 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 posted averages are not
       used in any way in calculating the final class
       average. GBA

Overall averages

        38 students took three or more tests (including
           the fourth test) and had at least 106 homework 
           points

           for these 38 students

            the final CPS average is  4.57 points (out of 5)

             the final HW average is  7.11 points (out of 8)

           the final quiz average is  6.21 points (out of 7)

           the final test average is 49.30 points (61.63% of 80)

              the overall average is 67.2  points  


Note that the overall average includes all students who took
three or more tests (including the fourth test) and who had
at least 106 HW points.  The test average is computed by dropping 
the lowest MC section and the lowest problem section for each 
student (except one section of test 4 must be kept), computing 
each student's average, and then computing a global average 
for all 38 students.  With this final average, the final grade
scale is 

           43.0  -  53.6     D
           53.7  -  67.0     C   (above 65.1 is C+)
           67.1  -  80.6     B   (below 70.0 is B-, no B+'s this year)
           80.6 and up       A   (no A-'s this year, above 91.1 is A+)

with below 43.0 as E.  The final scale was selected so as to
find gaps in the distribution.  With the scale as given above 
the highest E is 34.3, the lowest D is 47.6, the highest D 
is 50.9, the lowest C is 53.8, the highest C is 65.7, the 
lowest B is 67.1, the highest B is 75.2, and the lowest A 
is 80.8.  The smallest gap is 2.4 points between C and B.  
Grades were assigned strictly based on this scale.
