*******************************************************
The course average is 606.27; this includes the 20 bonus points
IN curving this is the bound of the B / C+ range
I am a bit more generous than curving though so students around
it should be in the B range 5/16

  General and Generic guidelines for grading
-----------------------------------------------------------------------------
RULE 1.
Final Exams at 25% of 345  = 86.25 receive an automatic F per 
Syllabus(Handout 1).
If letter grade is assigned here it is final; for all other cases 
it will involve RULE 2 and ADJUSTMENTS 1-3.

RULE 2.
Students are then groupped 'curve like' per half of standard deviation 
(usually 70-100pts).  Final Letter grades are decided for the remaining 
non-RULE 1 students.

ADJUSTMENT-1
RULE-2 students with (< 500 pts) but with  points at least  50% of top 
student's points and a Final   at MORE than 50% of top Final Exam 
grade  also get a C even if they have < 500 pts.

ADJUSTMENT-2
Otherwise, RULE-2 students in range 400-499 are assigned a D grade and
0-399 students are assigned an F grade.

ADJUSTMENT-3
Students at more than 500 points are assigned letter grades accordingly per
RULE 2. A violation (or violations) of the Collaboration policy of the course
adjust the final letter grade appropriately.

===========     ===========
N               =  number of students taking the exam
Interval        =  0 to maxpoints possible for exam (as in Handout 1)
Average         =  Sum of grades in exam divided by N
Stand Deviation =  Shows dispersion of grades. If ave is '37' and 
                   std is '12' this means that roughly 2/3 of the 
                   grades are within 37 +/- 12 , and 
                   95% within  37 +/-  2*12.
Median          =  Half of the students got that much or less 
                   (and half, more than that).
