       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).

       The final overall class average is 61.24.
       Thanks for a great semester. GBA

       Here is a histogram of the scores of still-active    
       students who have nonzero CPS scores and MP totals
       of more than 590 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
       twelve 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,
       because these average scores include 1 test drop out
       of 3 tests, whereas in the end you will only get to
       drop 1 test out of four, and because the final exam
       is not included, these overall scores may still be
       slightly higher than the final overall averages.

       The overall class average at this time is 65.29.

                           DISCLAIMER

       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.
       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 scores and MP totals
       of more than 350 in my online gradebook.  Soon, I
       will add some vertical red lines to indicate the
       approximate locations of the average E-D, D-C, C-B,
       and A-B cutoffs for the past twelve 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 possibly be.  As of 10/31, 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 2 tests,
       whereas in the end you will only get to drop 1 test
       out of four.

       The overall class average at this time is 66.5.
