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. GBA

Overall averages 

        73 students took all four tests

           for these 73 students 

             the final HW average is  22.5 points (90.1% of 25)

           the final test average is  54.8 points (73.1% of 75)

          and the overall average is  77.4 points


Note that the overall average includes all students who took
four tests.  The test average is computed by dropping the
two lowest test 'halves' for each student, computing each
student's average, and then computing a global average for
all 73 students.  Since the overall average is above 75
there is no curve.  The final letter grades are assigned
strictly based on the following scale:


                      60.0 - 69.9      D
                      70.0 - 79.9      C
                      80.0 - 89.9      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
between 10 and 11 AM Monday July 7.  After that time any
change of grade requires a change of grade form.  For
