       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).

       Here is a histogram of the scores of still-active
       students who have nonzero CPS grades and total HW
       points of 675 or more in my online gradebook.  The 
       red lines indicate the approximate locations of the 
       average E-D, D-C, C-B, and A-B cutoffs for the past 
       ten semesters in which I have taught PHY131, adjusted
       to find the large gaps in the distribution.  These 
       red lines will give you some idea of what your final 
       letter grade cutoffs might be.  As of 12/12, these 
       overall scores should be reasonably similar to the 
       final overall averages; however, the final exam is
       not yet included.

       The overall class average at this time is 62.02.


                           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 CPS and MP grades in my 
       online gradebook.  The red lines indicate the
       approximate locations of the average E-D, D-C, C-B, 
       and A-B cutoffs for the past ten semesters in 
       which I have taught PHY131, adjusted to find the
       large gaps in the distribution.  These red lines will 
       give you some idea of what the final letter grade
       cutoffs might be.  As of 11/28, these overall scores 
       should be reasonably similar to the final overall 
       averages; however, because these average scores 
       include 1 test drop out of 4 tests, whereas in the 
       end you will only get to drop 1 test out of five, and 
       because the final exam is not included, these overall 
       scores may still be slightly higher than the final 
       overall averages.

       The average letter-grade cutoffs shown here are only
       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.

       Here is a histogram of the scores of still-active    
       students who have nonzero CPS and MP grades in my 
       online gradebook.  The red lines indicate the
       approximate locations of the average E-D, D-C, C-B, 
       and A-B cutoffs for the past ten semesters in 
       which I have taught PHY131.  These red lines will 
       give you some idea of what your final letter grade
       cutoffs might be.  As of 11/09, these overall scores 
       are a bit higher that I would expect the final overall
       averages to be because the final exam is not included, 
       and because these average scores include 1 MC and 1
       free response test drop out of 3 tests, whereas in the
       end you will only get to drop 1 test out of five.
