NOTE:  In reporting the averages from the tests we drop
       the lowest scores.  This is because the lowest
       of the three tests will be weighted half as much
       as the other two in the final averaging.  This
       half-weighting is equivalent to dropping 1/6th 
       (or 16.7%) of all test scores.  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

    The details of the final grade scale were primarily
determined by the presence of gaps in the grade distribution.
Here is that final grade scale.  

      below 39.5    E
      39.5 - 45.3   D
      45.4 - 63.6   C  (above 57.4 is C+)
      63.7 - 76.8   B  (below 67.2 is B-, above 74.5 is B+)
      above 76.8    A  (below 79.7 is A-, above 90.0 is A+)

Letter grades were assigned strictly according to this
scale.  The highest E is 33.0, the lowest D is 39.5;  the
highest D is 43.4, the lowest C is 45.4;  the highest C
is 62.8, the lowest B is 63.7; the highest B is 75.7,
and the lowest A is 76.9.  The smallest gap between
levels is 0.9 points between C to B.
