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 test averages are not 
       used in any way in computing the final overall
       class average.  GBA

Overall averages

       64 students took three or more tests (including
           test four) and had more than 90 HW points

           for these 64 students

           the final PRS average is   4.49  points (out of 5)

           the final HW average is    6.18  points (out of 8)

           the final Quiz average is  5.81  points (out of 7)

           the final test average is 51.70  points (64.63% of 80)

          and the overall average is 68.18  points


Note that the overall average includes all students who took
three or more tests (including test four) and had more than
90 HW points.  The test average is computed by dropping the
lowest MC and the lowest Problems section for each student, 
computing each student's average, and then computing a global 
average for all 64 students.  With this final average, the 
final grade scale is

           49.9  -  59.7     D
           59.8  -  73.4     C   no C+'s this year
           73.5  -  81.5     B   (below 75.7 is B-, above 79.4 is B+)
           81.6 and up       A   (below 82.4 is A-, above 91.2 is A+)

with below 49.9 as E.  This final scale was selected so as to 
find gaps in the distribution.  With the scale as given above 
the highest E is 46.2, the lowest D is 49.9, the the highest D 
is 58.7, the lowest C is 59.8, the highest C is 71.4, the 
lowest B is 74.5, the highest B is 80.2, and the lowest A is 
81.6.  The smallest gap between levels is 1.1 points between D 
and C.  Letter grades were assigned strictly based on this scale.

     Be sure to check your TA's computation of your final grade.
