       Here is the final histogram.  In the histogram, solid
       lines indicate the major separations (for example,
       C+/B-).  Dotted lines indicate the minor separations
       (for example B-/B).  There were no A- or B- grades
       this year.

       The final overall class average is 72.34.
       Many thanks for working hard this semester. GBA

       Here is a histogram of the scores of still-active
       students who have nonzero TP grades and total HW
       points of 760 or more in my online gradebook.  The 
       red lines will give you some idea of what your final 
       letter grade cutoffs might be.  As of 5/02, these 
       overall scores should be reasonably similar to the 
       final overall averages; however, the final exam is
       not yet included, and will likely lower the overall
       average somewhat.

       The overall class average at this time is 75.52.


                           DISCLAIMER

       The average letter-grade cutoffs shown here are only
       an estimate of the final letter-grade cutoffs.  The 
       final selection of cutoffs takes into consideration
       the final class average and is generally primarily
       determined by the location of large gaps in the final
       distribution of overall averages.  The final cutoffs
       may be EITHER HIGHER OR LOWER than those shown here.
       Also, the plus-minus system will be used in the final
       cutoffs, but I will not estimate the location of those
       plus-minus cutoffs.

       Here is a histogram of the scores of still-active
       students who have nonzero TP grades and more than
       660 of the available Mastering Physics points.
       The red lines indicate an ESTIMATE of the approximate
       locations of the E-D, D-C, C-B, and A-B cutoffs
       for this semester.  

       The overall class average at this time, for these
       students with nonzero TP grades and WebAssign totals
       of more than 660 points, is 78.18.  Since this average
       includes 1 test drop out of 2 tests, and since in the
       end there will be 1 test drop out of 3 tests, and also
       the final exam will be included, it is expected that
       the final average will be lower than the current
       average.

                           DISCLAIMER

       The average letter-grade cutoffs shown here are still
       a rough estimate of the final letter-grade cutoffs.
       The final selection of cutoffs takes into consideration 
       the final class average and is generally primarily 
       determined by the location of large gaps in the final 
       distribution of overall averages.  The final cutoffs
       may be EITHER HIGHER OR LOWER than those shown here,
       however, at this time I would expect that they are 
       unlikely to be higher.  Also, the plus-minus system
       will be used in the final cutoffs, but I will not
       estimate the location of those plus-minus cutoffs.

3/29

       Here is a histogram of the scores of still-active    
       students who have nonzero TP grades and MP grades
       of more than 480 in my online gradebook as of 3/29.

       The overall class average at this time is 78.39.
