THE RULES BELOW DO NOT APPLY TO FALL 2020 or later as structure 
of the course has changed. They are however indicative of the
rules that will be used.
------------------------------------------------------------
RULE 1. INACTIVE
Final Exams at 25% of 333  = 83.25 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 70pts).  Final Letter grades are decided for the remaining 
non-RULE 1 students.

ADJUSTMENT-1
RULE-2 students below 500 are added excess points to determine if they 
can be assigned a C.

ADJUSTMENT-2
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-3
Students at more than 500 points use excess points provided Final Exam
grade is around the level of the Exam 3 grade of students in the upper group.
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 exam grades divided by N
Stand Deviation =  Shows dispersion of grades. Roughly, 2/3 of the grades are
                   within 37 +/- 12 , and 95% within  37 +/-  2*12 if ave is 37 
                   and std 12
Median          =  Half of the students got that much or less 
                   (and half, more than that).
